Singular value decomposition of 4x4 matrix. Computes the SVD of a 4x4 input matrix A as ![]() where U are the left singular vectors, S contain the singular values and VT are the (transposed) right singular vectors. NOTE: the contents of A are NOT destroyed. The singular values S are provided in decending order. This function calls the general SVD routine gan_mat_svd(). |
