Folks,

I'm in dire need of a singular-value-decomposition package
for arbitrary size (large) matrices.

If anyone has one already implemented and working in C,
I'd really appreciate it.
I have algorithms with non-C code,
but have been unable to write code from them that works.

Alternatively, if anyone can tell me in simple terms
what to do with the eigenvalues and eigenvectors of
A * transpose(A) and transpose(A) * A 
so that the three actually multiply together to form the original
matrix, I'd appreciate that too.

Please mail me at skh@nl.cs.cmu.edu internet, and I guess
...!nl.cs.cmu.edu!skh from a backbone sight on the internet
otherwise, and I'll post a summary on sci.math.num-analysis.
