Function Documentation

template<typename MAT_MxN , typename VEC_N , typename MAT_NxN , typename VEC_M >

void IsoEx::Math::svd_backsub	(	const MAT_MxN &	A,
		const VEC_M &	S,
		const MAT_NxN &	V,
		const VEC_M &	b,
		VEC_N &	x
	)

SVD backsubstitution. This is the implementation described in Numerical Recipies.

template<typename MAT_MxN , typename VEC_M , typename MAT_NxN >

bool IsoEx::Math::svd_decomp	(	MAT_MxN &	A,
		VEC_M &	S,
		MAT_NxN &	V
	)

Computes the SVD of A into U*S*V^T. A will be destroyed! The diagonal matrix S is stored as a Nx1 vector. This is the implementation described in Numerical Recipies.
