I can run now "make check", but I'm seeing the same problems as Thomas 
in the galois code:

Okay I'm using the ugly genpath and I've removed the fem_test.

Let me know if there are any other problems.

That is because HAVE_CONFIG_H is not defined.  Looking at the
makefile it should be defined automatically but your build.log
doesn't show it on the command line.

I've checked out OF from Anonymous CVS and done the first three of the
above against 2.9.6 on Ubuntu Dapper on intel hardware. It doesn't work
for me. So far I've seen the following errors that all seem to come from
some autoconf magic that I don't know anything about:

*) TYPEID_HAS_CLASS is not defined. This means that the
DEFINE_OV_TYPEID_FUNCTIONS_AND_DATA gets called with 2 arguments, and
not 3 as it should.

*) HAVE_ND_ARRAYS is not defined either. This means that
octave/Array2.cc gets included in fixed/Array-f.cc. This is a problem
because Array2.cc doesn't exist.

*) ffft.h and fixed_inc.h in main/fixed/examples both includes "fixed.h"
but can't find them.

I've hacked my way around these issues, but I still get the following

[OctDev] multiplication, inversion of toeplitz matrices

[Gorazd B. <br...@hi...>]

Hi all,

Is there a method to multiply a toeplitz matrix with a vector, or
multiplication of two toeplitz matrices or the inversion of them.

If not, I can provide them in some time since I am using them, for the
inclusion into octave-forge.

what is the exact procedure for submitting code??

thanks a lot,
gorazd

I tested octave-forge on a Fedora 5 (gcc 4.1.1) on AMD 64-bit. I think
that I have most dependencies installed (qhull, gsl, nc-dap, ginac,
ImageMagick-c++, pcre). I got no errors for the compilation (but some
warnings: &#8216;print_usage&#8217; is deprecated). The "make check" however, fails
with the following error:<br>
<br>
[...]<br>

<br>
I think the error comes from the LOADPATH line in batch_test.m. I
changed batch_test.m to use the addpath/genpath function:<br>
<br>
diff batch_test.m batch_test.m.orig<br>
9,12c9<br>
&lt; addpath(genpath("main"))<br>
&lt; addpath(genpath("extra"))<br>
&lt; addpath(genpath("nonfree"))<br>
---<br>
&gt; LOADPATH = "main//:extra//:nonfree//:";<br>
<br>
<br>
Now batch_test complains that he can't find "fem_test". It seems that
this function is no longer in octave-forge.<br>

A first version of the package system is in 2.9.6, so hopefully this
release would be the last or second-last release of octave-forge as a

Refactoring octave-forge into packages would be alot easier (at least

Well, it doesn't look like we'll get the code repackaged for the octave
package manager in the short term, so a new release is problem a good
idea. Up till now only Paul has done releases, but as he is taking time
out for other things, someone else should probably do the release.
Basically as this is just a 2.9.6 release a lot of the test that Paul
did for compatibility between version won't be needed, which will make
the job easier..

[OctDev] New release?

[Quentin S. <qsp...@ie...>]

Now that 2.9.6 is out and octave-forge CVS is at least somewhat 
synchronized with the state of octave, I'd like to suggest a new 
snapshot release. The last release is now quite far out of date with 
respect to 2.9.x development.

Given that the current core function is an m-file and the new code is an
oct-file with a dependency on a C file, this needs some thought.

[OctDev] list of primes using D. Bersteins fast primegen library

[Dr.-Ing. T. F. <fi...@ig...>]

Dear Octave Developers 

attached you will find a tarball containing a few little functions to
- calculate list of primes in given ranges
- calculate number of primes up to given bound

those functions are based on D. Bernsteins primegen library, that provides
very fast O(N) functions. These functions calculate the list of primes up to 10,000,000 
15 times faster than the well known octave-forge function primes(). The
advantage grows with increasing bounds.

I am Himanshu Singh Chauhan from Jaipur (India). I am a final year MCA
student.
I wish to be a part of Octave developers.

Most of my work is Audio Signal Processing, so most of my submissions
will be
on audio signal processing files.

regards
--Himanshu

[OctDev] delaunayn bug fixed

[Alexander B. <ab...@ma...>]

Hi all,
I checked a bug fix for delaunayn in octave-forge.
The problem was that qhull returned non-simplicial facets (for example 
squares instead of triangles).  The return matrix was then too small to 
hold all vertices of these non-simplicial facets.

Now delaunayn calls "qh_triangulate()" and it should decompose all 
non-simplicial facets and if it doesn't, an error message (other than 
core dump) is printed.

Also, I changed the default options provided to qhull to match those 
that matlab uses. Let me know if this has any negative effects for your 
data.

It is now also possible to provide those options as a cell array of 
strings as in matlab.

Cheers
Alex

[OctDev] plan to submit some functions in combinatorics

[Dr.-Ing. T. F. <fi...@ig...>]

Dear Octave Developers, 

may I ask politely to get an octave-forge account, since I plan 
to contribute some functions concerning combinatorics (actually I do use them
for some purposes in algebra):

- calculate integer partitions for a given number N. 
  For example, given N = 4, then it can be added up from lower integers as 
          4 = 4 * 1
            = 2 * 1 + 1 * 2
            =         2 * 2
            = 1 * 1         + 1 * 3
            =                 1 * 4

  so the partitions of 4 can be represented as 

            4  0  0  0
            2  1  0  0
            0  2  0  0
            1  0  1  0
            0  0  0  1
  

- calculate the whole number of possible integer partitions for given 
  number  N. For example the number 17 can be written in 297 distinct sums. 

- calculate prime factor decomposition of factorial(N). 
  For example, given N = 7:

     7! = 2^4 * 3^2 * 5^1 * 7^1

  So the result would be given as the vector (4, 2, 1, 1). 



Maybe some more...

Best regards


Torsten Finke

Sorry, no time to look more in detail.

[OctDev] delaunayn makes octave crash

[Alexander B. <ab...@ma...>]

Hi all,

I have a problem with delaunayn under octave 2.9.5. The following code 
make octave crash:
n = 3;
x = repmat(reshape(1:n,[n 1 1]),[1 n n]);
y = repmat(reshape(1:n,[1 n 1]),[n 1 n]);
z = repmat(reshape(1:n,[1 1 n]),[n n 1]);
P = [x(:) y(:) z(:)];
T  = delaunayn(P);

I have this problem with delaunayn from fedora core 5 
(octave-forge-2006.03.17-4.fc5) as well as with the current CVS version 
of octave-forge (I changed the print_usage() manually to 
print_usage('delaunayn') to compile with octave 2.9.5 instead of octave 
CVS).

The delaunayn function crashes at the line "qh_freeqhull(!qh_ALL);"

Any ideas ? Can anybody confirm this bug?

Some information about my system:
AMD - 64
gcc 4.1.1
qhull-2003.1-5.fc5

Cheers
Alex
