WebAll usage of this module starts by calling one of four functions, all of which return a Factor object, documented below. Most users will want one of the cholesky functions, which perform a fill-reduction analysis and decomposition together: sksparse.cholmod.cholesky (A, beta=0, mode="auto", ordering_method="default", use_long=None) ¶. Weblinalg.slogdet(a) [source] #. Compute the sign and (natural) logarithm of the determinant of an array. If an array has a very small or very large determinant, then a call to det may overflow or underflow. This routine is more robust against such issues, because it computes the logarithm of the determinant rather than the determinant itself.
