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.
