opencv has an implementation and seems to use a minimal 'keep the
copyright' license...

Hi,
it'd be good to put a C++ version of the SVD into TooN - this turns
out to be much faster than LAPACK for small matrices and eliminates
dependence on LAPACK, both of which are good things for e.g. iphone
stuff.
Currently I'm using a c++-ified port of the numerical recipes
algorithm, but numerical recipes is notoriously difficult with
copyright. Any guesses if porting the c-code to C++ is enough to get
around copyright, or better not?
Otherwise I can go back to the FORTRAN code which NumRec used to
make their C version.
