void singularValueDecomposition	(	sample **	a,
		int	m,
		int	n,
		sample *	w,
		sample **	v
	)

Given a matrix a[m][n], this routine computes its singular value decomposition, A = U*W*V^{T}. The matrix U replaces a on output. The diagonal matrix of singular values W is output as a vector w[n]. The matrix V (not the transpose V^{T}) is output as v[n][n]. m must be greater or equal to n; if it is smaller, then a should be filled up to square with zero rows.
