(open source) Linear Algebra code?

AirDragon — Tue, 08 Nov 2011 08:48:16 GMT

Hellos,

Does anybody know if there's an open source code project that works with matrices, vectors, and the like? So far I've found something called Armadillo, but it looks like it's compiled only for PC's.

I basically just want a few functions to work with, since I'm working with quite a few physical data and would like a conveniant form to put them in. Plus, there's a couple of control functions out there that work exclusively with matrices and the like.

If there isn't one around, then I'll probably end up making one myself... but you would think that matrix boilerplate would be available somewhere, right?

Many Thanks,

AirDragon

P.S.

I'm sorry, but I really didn't know a good place to put this. I did think of the CodeWarrior forums but wasn't sure. It would be much oblidged if a mod would move this to the right place...

Hi,

The best I know is "Numerical Recipes in C: The Art of Scientific Computing".

The second edition (1992) is free on the internet. See chapter 2.

Regards,

Ipa

Many thanks, I'll see if I can go through the book tonight.

Also a big thank you to JediMaster for the move!

Hi AirDragon

I've tried to solve a problem similar to the one you described on the post above ( having the same problem to embed armadillo on mqx).

Did you achieve any kind of solution? Particularly I need support to run the Gauss-Newton algorithm or any other similar to solve the nonlinear least-squares problem.

I really would appreciate if you share your solution/tips with us.

thanks in advance.

Unfortunately, no. The project was shelved sometime after posting this. There are a couple of life-related issues that are preventing me from diving back in at the moment. As soon as I can get a proper work area again, I'll restart.

Please have a look at AN4489 Using CMSIS-DSP Algorithms with MQX
