Free Numerical Integration Software

[CycloWizard]

Does anyone know of a free numerical integration program that isn't based on MATLAB? It would be great if it could do quadrature integration, but that might be asking a bit much. I'm hoping I don't have to write my own, since I'm a bit rusty.

I posted this in the software forum first, but figure the people who read this forum are more likely to know what I'm talking about. Thanks!

heh i dont know what quadrature integration is but ive used Maxima as a quick substitute for MATLAB

Thank you sir - haven't heard of it, but I'll certainly give it a try. :beer:

Come on, break out the FORTRAN! You know you want to...

*shudder* I've had to teach myself 7 languages in the last semester, I'd prefer not to add another one. Besides, can I get FORTRAN for free? We have it in the labs, but pulling solo all-nighters in a room actually called the CELL (Chemical Engineering Learning Laboratory) is just plain depressing. 😛

Yes, the GNU Fortran compiler, g77, is free. However, FORTRAN's not the language I would choose to use.

You know 7 languages, I assume you mean programing?? So you can write a computer program?

If you are a programmer check out the Numerical recipes page or go to your local book store and find a book on numerical methods. You will be surprised at how simple the algoritm of some very good methods are.

I can, but I doubt it would be nearly as good as MATLAB. I'm a casual programmer - I do it when I have to, so I usually have to scrape my way through whatever I'm doing to get results. I just found out my department has a MATLAB site license though, so I'm done. 😀

Try Force 2.0.8 if you want a GUI in Windows. I use it with XP and it works fine with both F77 and F90. It's free and you can get it from download.com.

CD.

Octave?

Why not? Fortran is fast and very simple to program in. It is a great scientific computing language that never gets enough credit.
