Thank you for your suggestions. I will go to work again.

Thank you for your suggestions. But I have some remarks:

1) It is not hard coded. If you include the headers "lapack.h" and "blas.h" (see also "factor.h") it will automatically add underscore during preprocessing.

2) I will correct that.

3) For which versions is this?

4) This option is already included in make_factor.m

5) There is already a make_factor.m included for building the mex-files.

Thank you very much.

Your code was very helpful in the creation of my own high-accuracy real-time S-Function rate limiter.

Cheers!

Great submission, very useful for a lot of purposes! But I found out that there might be some bugs, or maybe it is only because of my Matlab version (2012a), I'm not sure..

For example, when I want to get the QL-decomposition, it's fine for square matrices, but for any kind of non-square matrix, I get a fatal error and Matlab shuts itself down. Did anybody also notice such kind of error?

Thanks.

I'm working on video recording, but with pause(n) I can hardly get right frame rate. This really helps me out!

PLS is there anyone used this function in signal processing???
If there is anyone could you please refer me to any article who used it in signal processing. This part is important for me to do my thesis so I understand more about this fucntion in signal processing and to put some references.
I couldnt find any

THANKS
