result = Matrices.det(A);
This function returns the determinant "result" of matrix A computed by a LU decomposition with row pivoting. For details about determinants, see http://en.wikipedia.org/wiki/Determinant. Usually, this function should never be used, because there are nearly always better numerical algorithms as by computing the determinant. Examples:
Type: Real[:,size(A, 1)]
Description: Determinant of matrix A
