Matrex / News: Recent posts

Matrex, the matrix spreadsheet, has released version 2.2.
Main changes:

- 42 new functions, included database update and unit conversion.
- New dates handling.

Download from: http://sourceforge.net/projects/matrex/files/Matrex/2.2

Matrex 2.1 has been relased.
Main changes:

- Now tables/grids have real row headers.
- The script editor has become an IDE to write and test scripts.
- Help button on every window.

Download from: http://sourceforge.net/projects/matrex/files/Matrex/2.1/

If Matrex was installed in the "C:\Program Files..." directory, there was the possibility that the Matrex 2.0 menu shortcut in Windows did not work, because of the spaces in "Program Files".
The new version, Matrex 2.0.1 (only for Windows), solves this problem enclosing the Matrex path in double-quotes.

Matrex 2.0 has been released.

Changes:
Matrex can be optionally used in a client/server architecture making it possible:
- for several users to work together on projects/sheets
- for single users to delegate the calculations to a server

Matrex 1.3.8 has been released.

Changes:
- It uses a reasonable amount of memory when importing large CSV files (Bug 2854282)
- Applied patch of Nikolay Zamosenchuk to fix a performance problem when selecting cells in tables

I updated the adapter matrexjruby.
Matrexjruby allows Matrex to use JRuby as a script language.
Now matrexjruby works with Matrex 1.3.6 and it can be installed in a separate directory.

This new version works for Java 5 and Java 6 in MacOSX, thanks to SWT 3.5.
Incompatibilities with Java 5 have been fixed, together with some potential problems maximizing the main window.

The Matrex adapter for Scilab is an adapter to use the functions of Scilab inside Matrex.The idea is to add functions to a Matrex project that contain calls to Scilab.The purpose can be:
- Let Matrex calculate special functions (or that you added to Scilab)
- Use Matrex as graphical front end for Scilab
The current version of the adapter has been tested on Scilab 5.1.

Matrex 1.3 has been released!

Matrex is the spreadsheet that uses blocks/matrices, not cells.
Multiple threads are used to recalculate the sheets, making Matrex scalable on many processors.

Version 1.3 gives:

- easy to use GUI
- candle and high/low charts.
- multiplatform setup (generic)
- callbacks

Matrex 1.2 has been released!

Matrex is the smart alternative to spreadsheets which calculates by blocks, not by cells, and uses real multithreading for the calculations.

With version 1.2 is possible to use SQL to filter, aggregate and sort the content of the spreadsheet.

The changes from the previous version can be found in http://matrexblog.blogspot.com/2008/02/matrex-12-released.html

I updated the adapter matrexjruby.
Matrexjruby allows Matrex to use JRuby as a script language.
Now matrexjruby works with JRuby 1.01.

Matrex 1.1 has been released!

Matrex is the smart alternative to spreadsheets which calculates by blocks, not by cells, uses threads and can be used as desktop application or library.

The changes from the previous version can be found in http://matrexblog.blogspot.com/2007/04/matrex-11-released.html

Matrex has now a GUI help on line, on http://matrex.sourceforge.net/help/index.html

With this adapter you can build Matrex functions that call Scilab code.
Good if you want to work with complex calculations in Matrex or if you want to use Matrex as graphical front end for Scilab.
This version works with Scilab 4.1. Moreover, it allows safer multitasking, because it uses a shared singleton to call Scilab.

Matrex_R allows to transform a Matrex calculation to a call to an R function.
This adapter transforms Matrex to a front-end for R.

A guide that shows how to write functions (formulas) in Matrex (http://matrex.sourceforge.net) projects.
You find it in http://matrex.sourceforge.net/doc/templatesguide.pdf.

Matrexmatlab is the adapter that lets Matrex use Matlab for the matrices calculations and that gives to Matlab an event driven GUI based on matrices.
After a year matrexmatlab 1.0 has finally been released!

Version 1.01 works with JRuby 0.9.1. Also, the use example is more complete.

The version 1.0 of the Matrex Client/Server specification has been published (for the future Matrex 2.0).
You can find it in http://matrex.sourceforge.net/doc/clientserver.pdf.

Matrex 1.0 final has been released!

Matrex is the smart alternative to spreadsheets which calculates by blocks, not by cells, uses threads and can be used as desktop application or library.

The changes from the previous version can be found in http://matrexblog.blogspot.com/2006/11/matrex-10-final-released.html

The Matrex sample project that uses a database has been updated to fix the contracts result calculation.
To calculate correctly the results the functions "tail", "tailas" and "size" has been added.

matrexdb is a Matrex project that works with an embedded database, using the "query" function template.
The database contains the data for the year 2006 of a fake "chocolate market". Products, spot and closing prices and contracts.
The project contains a presentation (2006 positions) and some charts.

It is a technical document that shows how Matrex works internally.
Useful for Matrex users to understand and have better control on it and for developers to know how to work with it.
The document is in the "Documents" section in the Matrex site, http://matrex.sourceforge.net

Use Matrex the un-spreadsheet (http://matrex.sourceforge.net), instead of spreadsheets when working with vectors (for example database data, charts) and matrices.
The changes from M2 to RC1 (release candidate 1) include more user friendly GUI, improved stability, code modularization. New features are info navigation, matrix editor customized headers, support for big matrices.
