Mmmhh, then it looks like it's time to debug
LinearAlgebra.singular_value_decomposition(). Not exactly what you wanted to
hear, is it? :)
Sorry I can't give a better answer at this point. Why don't you try computing
the SVD of your matrix (you said it was 26x26 only) in Mathematica or
something? It might hint at where the problem is. Other than that all I can
say is, roll up your sleeves and fix the Numeric SVD routine. Many will thank
you :)
FWIW, I've used the Numeric SVD without problems, so at least in some cases it
works.
Cheers,
