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 on

[Numpy-discussion] SVD errors

2009-02-02 Thread mtrumpis
Hello list.. I've run into two SVD errors over the last few days. Both errors are identical in numpy/scipy. I've submitted a ticket for the 1st problem (numpy ticket #990). Summary is: some builds of the lapack_lite module linking against system LAPACK (not the bundled dlapack_lite.o, etc) give a
