Ill Conditioned incorrent Output zgesvd_, platform : VC++

Postby neo.patrix » Tue Sep 25, 2007 3:27 am

Hi all,

I have a problems with using zgesvd_ in VC++

1) The function doe snot exist in clapack.h. I fixed that thing seemingly. I created a function declaration of using original LAPACK ZGESVD routine. The
program complies successfully with new function declaration.

2) The output that I get from zgesvd is no where near to any sain correctness
compared to MATLAB svd which uses same ZGESVD function. The output is terribly ill-conditioned. This is the thing which SVD should solve in first place.

3) This is urgent, I have got deadlines.

thanks
Pratish.
