Comments:
This is an attempt to replace the numerical recipies code. its is not as good, so it is suggested you use the routine in MatrixC. A class that holds U,V,Sig - the singular value decomposition of a matrix

SVDC(const MatrixC & A)

Decompose Matrix A, of M rows and N columns, M>=N

void cut_off(const double min_sig)

Regularization: make all sig(i) that are smaller than min_sig exactly zeros Inquiries

const MatrixC & GetU(void) const

Access U matrix.

const MatrixC & GetV(void) const

Access V matrix.

const VectorC & GetSig(void) const

operator MinMax(void) const; // Return min and max singular values double q_cond_number(void) const; sig_max/sig_min
