The problem is that either all of those have to be unpacked, or they have 
to be listed in the file "webFunctionsList.dat" in the .jar, which must be 
generated using the function "createfunctionslist".

In our (unfortunately failed) GSoC project for Fiji (the student was just 
not able to properly analyze the source code, let alone the challenges of 
the project), we wanted to provide a way which reads the .jar file 
directly, avoiding the need for a file webFunctionsList.dat.  That would 
have allowed us to make an embedded interpreter with new functions 
provided by us.

It is in the class jmathlib.ui.text.TextUI.

Re: [Mathlib-develop] Doubt of a new member

[Alejandro T. <ate...@ho...>]

Hi Ven,

 

JMathLib supports both .class based functions and GNU Octave's .M files.

 

You can take a look to the supplied .m files at http://mathlib.svn.sourceforge.net/viewvc/mathlib/JMathLib/tags/release_v00_09_00/src/jmathlib/toolbox/statistics/base/center.m?revision=415&view=markup in example.

 

IIRC JMathLib supports a command-line interpreter, but I'm afraid I don't remember the exact location.

 

Regards,

Alejandro.

[Mathlib-develop] Doubt of a new member

[Paulados <pau...@ya...>]

Hi everybody,

I'm new in JMathLib. I have look for a substitute to matlab, and I have found JMathLib. But I have some doubts.

* I run JMathLib on Ubuntu8.04 using java 1.6

1) I would like to know how could I add new functions to JMathLib (java or mfile functions) as I have not found it on the web.

2) I would like to know how could I run just a script from console as an autonomous program. It is to say, something like:

java -cp bin jmathlib.ui.text.TextUI miscript.m

But it seems... it is not the right way.

Thanks in advance,
Ven

Re: [Mathlib-develop] JMathLib and image processing

[Alejandro T. <ate...@ho...>]

Hi Martin,

 

I apologize for the delay of the answer.

 

No, JMathLib doesn't support image processing yet, but I think that it could be easily integrated into Fiji or implemented in JMathLib.

I did some contribution to the stats toolbox but the big contributers were Mr. Müller and Mr. Sparshatt.

 

Regards,

Alejandro.

[Mathlib-develop] Introducing the Fiji project

[Johannes S. <Joh...@gm...>]

Hi JMathLib developers,

I am one of the developers of Fiji (http://pacific.mpi-cbg.de/), an image 
processing suite based on ImageJ (http://rsb.info.nih.gov/ij/).

As a lot of scientist use Matlab to prototype their image processing 
algorithms (and never manage to bring the algorithms out of prototype 
stage), it was pretty natural to try to find some way to run those scripts 
in Fiji.

A little search revealed JMathLib as a pretty mature Matlab clone without 
the licensing issues of the original.  Great job!

So we posted this as one of our GSoC ideas:

http://pacific.mpi-cbg.de/wiki/index.php/SoC2009Ideas#Add_JMathLib_.28Matlab_clone.29_support

Roughly, the idea is to include JMathLib as-is, and override the image 
toolbox to access ImageJ structures.

We got accepted as an organization into the Google Summer of Code, but 
nothing definitive will be known about the accepted projects until April 
20th.

Ciao,
Dscho

P.S.: I am aware that one of our applicants sent a mail to this list, but 
I wanted to introduce us properly.

[Mathlib-develop] JMathLib and image processing

[Martin H. <mar...@gm...>]

Hi folks,
I have applied for GSoC for Fiji project that would aim at integrating
JMathLib to Fiji to allow processing of images using .m scripts (this
would probably mean extending JMathLib as well to provide
functionality needed). I would like to ask what state is JMathLib with
respect to image processing?

Re: [Mathlib-develop] decimal point versus decimal comma

[Stefan M. <st...@he...>]

Dear BB,
the mentioned bug regarding "," and "." has been fixed over christmas.

It has to do with the Locale set in JMathLib. For the output of numbers
I have set the local to english. Hope this solves all issues.

Regards,
  Stefan.

[Mathlib-develop] Running script files

[Ν. Π. <mpa...@gm...>]

Dear JMathLib users,

i am a beginner to JMathLib. I learn it quite easily, because i am using
octave for years.

The only problem i have learning JMathLib are the script files.

I cannot figure out how can i run my m-files? Can you help me?

Thanks anyway,
Nick

[Mathlib-develop] Using library functions

[josu j. <jos...@eh...>]

Hi

This is my fist time using JMathLib and I think that is very  
interesting. After trying the software, i have the next  question:

Is it possible to use the Libraries/functions without the console?

Thank you in advance

Re: [Mathlib-develop] archive path?

[Stefan M. <st...@he...>]

Dear BB,
sorry for all the trouble:

This is my setup:
Menu Project/Properties
then select "Java Build Path"

click on "Source"
"Source folders on build path:" i have one entry "JMathLib/src"
"Default output folder" i have "JMathLib/bin"

click on "Libraries"
click on "Add JARs" and select "dynamicjava.jar" from the file selection

That should do the job.

If it doesn't work. I can send some screenshots.

Regards,
   Stefan.

[Mathlib-develop] archive path?

[bb-543437 <bb-...@ve...>]

Dear Stefan,

I still try to compile JMathLib_0.9.0 with eclipse now. I think I did a 
step forward.

In my last test I had the idea to remove the bin directory. To my 
opinion that directory bin must be created by the compilation of the 
source. I get a strange error message:
The archive: 
/JMathLib_0.9.0/bin/jmathlib/plugins/dynjava/dynamicjava.jar which is 
referenced by the classpath, does not exist. Certainly. a library might 
reside everywhere the program has excess to, but a path to a directory 
that should be created and is not existent at compile time does not make 
any sense to me. As I understand the structure of the code, the library 
files of dynamic java are a part of the src here?

I did some different trial runs with Java > Build Path > Classpath 
Variables 
<javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.jdt.ui.preferences.ClasspathVariablesPreferencePage)")>
So I tried in the user libraries
jmathlib\plugins\dynjava\dynamicjava.jar
in different variations, for instance 
src\jmathlib\plugins\dynjava\dynamicjava.jar, 
.\jmathlib\plugins\dynjava\dynamicjava.jar. But the message described 
above stays inmdependent of that entry. So one might argue, that there 
is a path set anywhere in the sources? Do you have an idea where this 
comes from?

So I argue that there is set any path in the source?

By the way
Is there any more help possible?

Regards
BB

Re: [Mathlib-develop] errors again

[Stefan M. <st...@he...>]

Dear BB,
what kind of development tool do you use?

I am using Eclipse: there simply add the jar file in 
jmathlib/plugins/dynjava/dynamicjava.jar to your library directories.

On the command line I compiled the java file
jmathlib/plugins/dynjava/JavaPlugin.java like the following

javac -classpath .;jmathlib/plugins/dynjava/dynamicjava.jar 
jmathlib/plugins/dynjava/JavaPlugin.java

You need to include the path to dynamicjava.jar

In case you do not want to try on: just remove the dynjava-directory and 
  errors with might follow.

Hope this helps,
   Stefan.

Re: [Mathlib-develop] concluding remarks

[Stefan M. <st...@he...>]

Dear BB.

plot[(1,2,3]) will through an error because the brackets are wrong.

Please use plot( [1,2,3,4] ) instead.

For compiling JMathLib i personally use Eclips and switched of some 
minor warning. You may be right, it would be a good thing to remove
warning from the code.

Please send me the most annoying warnings.

Regards,
   Stefan.

Re: [Mathlib-develop] bug report v. 0.9.0

[Stefan M. <st...@he...>]

Dear BB,

please download the current sources from SVN. As you found out the 
previous versions of JMathLib-installer and the ZIP-file do not
include the file dynamicjava.jar

I already changed the build script for JMathLib releases. The file
will be included in the next release.

With kind regards,
   Stefan.

Re: [Mathlib-develop] make.linux.sh/ sources for GUI-version

[Stefan M. <st...@he...>]

Dear BB
I am still confused why you are looking for
files in MathLib/Classes. The aformentioned directory names are really 
old. All class-files and source-files are available in the ZIP-file
from Sourceforge at

https://sourceforge.net/project/showfiles.php?group_id=24886&package_id=17259&release_id=605304

Hope this helps,
   Stefan.

Re: [Mathlib-develop] bugreport linux version

[Stefan M. <st...@he...>]

Dear BB,
I don't have such errors on windows.

Maybe your problem comes from renaming the directories from JMathLib to 
MathLib.

I think it should be possible to run JMathLib on linux by downloading
the ZIP file and running
java -cp bin jmathlib.ui.awt.GUI
in the top directory.

Please comment.

Regards,
   Stefan.

Re: [Mathlib-develop] JMathLib installation

[Stefan M. <st...@he...>]

Dear BB,
i just read your email.

As it turns out the documentation is really old regarding manual 
starting of JMathLib.

The part about starting has been written when JMathLib was still
called MathLib.

There are acutually two GUIs in JMathLib 0.9.0.
One is a conservative AWT and one is a swing type.

from the main directory:

java -cp bin jmathlib.ui.awt.GUI

or

java -cp bin jmathlib.ui.swing.SwingGUI

I just committed the documentation change to SVN.


Could you please supply the "start" file for Linux? (I am no linux user, 
windows only)

Kind regards,
   Stefan.

Re: [Mathlib-develop] PARSER: missing

[Stefan M. <st...@he...>]

Dear BB

You made a typo.

Please type
plot([1,2,3]) instead of
plot[1,2,3])

Reason:
plot( .... ) is a function call
[1,2,3] is a vector of data

Hope this helps,
   Stefan.

[Mathlib-develop] PARSER: missing

[bb-543437 <bb-...@ve...>]

Just because of frustration I tried JMathLib in the Demoversion of the 
homepage of JMathLib at Jily 5th at 17:50 , that worked about 2 days ago 
very well. And what did I get? See here:

 > plot[(1,2,3)]
??? plot[(1,
PARSER:  missing )

What the hell happens there?

[Mathlib-develop] concluding remarks

[bb-543437 <bb-...@ve...>]

JMathLib compatibility:

openSUSE 10.3:
You are using the following browser: Mozilla/5.0 (X11; U; Linux i686; 
de; rv:1.9.0) Gecko/2008061600 SUSE/3.0-1.1 Firefox/3.0 - InputPanel
You are using the following browser: Mozilla/5.0 (compatible; 
Konqueror/3.5; Linux) KHTML/3.5.7 (like Gecko) SUSE - InputPanel
Konqueror Version 4.0.3. (KDE 4.0.3) "release 17.1" -no InputPanel

openSUSE 11
You are using the following browser: Mozilla/5.0 (X11; U; Linux 86_64;

K Desktop Environment Version 3.59 "release 49.1" - InputPanel

In ANY case i get the message
 > plot[(1,2,3)]
??? plot[(1,
PARSER:  missing )
 >

About my trial to compile the project myself I have already reported.

In the menatime I got the code to the point to compile without error, 
but I get 353 warnings of the kind - this variabel will not be used....

I argue that there is the fundamental parser file missing?

What to do now?

[Mathlib-develop] error sources?

[bb-543437 <bb-...@ve...>]

I fixed the source of the errors to the class JavaPlugin.java in 
jmathlib. (May be I am wrong?)

There left two questionable lines, as one might see very clear:

/**Class containing the extensions of jmathlib*/
public class JavaPlugin extends Plugin
{
   
    private koala.dynamicjava.interpreter.TreeInterpreter 
djInterpreter;  ?????

    //private String name;  ?????
   
    public JavaPlugin()
    {

        name = "JavaPlugin";
       
        djInterpreter = new TreeInterpreter(new JavaCCParserFactory());

       
   
    }

There is the last class separated by a blank? Afaik is that not in 
coincidence with the  syntax rules of java? And there is something 
defined private but without any type definition? And that is also true 
for ther variable name, as type definition is marked as a comment 
(//private String name;)?

I checked the class-library 
(jmathlib/plugins/dynjava/koala/dynamicjava/interpreter.) and could not 
find a class djInterpreter. There is only a class TreeInterpreter. One 
can reduce the number of error messages to two in changing that lines to

    private koala.dynamicjava.interpreter.TreeInterpreter.Interpreter;

But that does not work either. I know that that does not mean that the 
error is removed, but it is a distinced hint.

I do not have any idea how that will be correct, because I do not 
understand that huge project in detail. But I am sure that the 
developers will know that. And there are lots and lots of messages of 
the kind "file not found".
