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.
