C code for Moore-Penrose inverse.(pinv in matlab)

[Oded]

Hi
I am looking for C code for Moore-Penrose inverse.
Now my partner and i need to convert matlab code to a
c code as a University project and there is a use in
the pinv command in the matlab code.
Does anyone have a code for the Moore-Penrose inverse
Thanks.

The pseudo inverse computations are based on the Singular
Value Decomposition. There is (or at least used to be) a
free numerical library (LAPACK) available where such
routines are included. I think I have seen the library
available for c/c++.

If I am not mistaken, a certain Dr Moler was involved in
developing LAPACK?

In article <6b69bf75.04053...@posting.google.com>,

The best way to compute the Moore-Penrose pseudoinverse
makes use the Singular Value Decomposition. See the "pinv"
function in MATLAB.

A Google query for C code for SVD finds several possibilities.
Straightforward JAVA code for the SVD that could easily be
translated into C is available at:

Good luck.

Does your university have a license for Simulink, RTW, and DSP Blockset? If
so, this is simple: you can readily generate embeddable C code for SVD or
PINV, since both blocks exist in DSP Blockset. --Don
