I played around with a C translation of that test program, and found that dgesvd (but not dgesdd) happens to converge and return all non-negative singular values for both operators I was having trouble with. I'm also looking at the Octave code just now, and I think they're using dgesvd also. Any one know why numpy uses dgesdd? speed?
Yes.
Hello Everyone,
I am trying to write my own svd function to use the "dgesvd" method from lapack, but my problem is that I cannot find the "dgesvd" method from this import "from numpy.linalg import lapack_lite".
Do I have to install lapack on my system(Ubuntu 13.04 64-bit)? I want to get the same results as MATLAB 2011b which is why I am trying to write a slightly different svd function than the function from "numpy.linalg.svd".
I would appreciate your help, Thank you. Amir
