Math library for Free Basic

[jdebord]

/me smells the possibility for a free (as in mind and beer) competitor for programms like MathLab or Derive

There exist free MatLab clones, e. g. SciLab (http://scilabsoft.inria.fr/)

I meant those that you trew something like f(x)=4x+(3x^3)-(16x^5) at the head and the programm does the full derive.

Have you looked into the possiblity of adding a Math Parser to the library. That would be very useful.

I use Maple for symbolic calculations.

There are free softwares for this too, e. g. JACAL (http://www-swiss.ai.mit.edu/~jaffer/JACAL.html), but I have not tested them.

However, my library is for numerical calculations. My goal is to provide a free alternative to the 'Numerical Recipes' software
which is not free, and for which the Basic and Pascal versions are no longer developed.

Yes, but I need a model. I am not skilled enough to code it myself. If someone wants to contribute... :wink:

[jdebord]

The library has been updated:

* Added a complex type
* Added several functions for finding roots of polynomial

More matrix functions (eigenvalues/eigenvectors) will be added soon.

What about making GSL available to FreeBasic,

Its not a bad idea... I've looked at calling some other math packs from FB as well...just not that hard :-)

[jdebord]

Usually I prefer translating Fortran routines. I am not familiar with C.

[keeling]

Yes, but you wouldn't have to translate the code, just call the libraries. http://www.netlib.org/ has several good, multi-platform libraries.

I haven't tried calling libraries in FB yet, and I understand the desire to translate (and the preference of ForTran over C) but this might be an avenue to explore.

[alexsee]

I was under the impression that all that needs to be translated for FB are the header files. GSL is multi-platform coded in ansi C. I made the suggestion because this library has been in development for years as a free replacement for Numerical Recipes. Further it comes with a comprehensive manual.

That said, it may be GPL'ed rather than using LGPL.
