Expand description

computes the numeric values of the cholesky $LBL^\top$ factors of the matrix $A$ with intranodal pivoting, and stores them in l_values

§note

only the lower (not upper, unlike the other functions) triangular part of $A$ is accessed

§panics

the symbolic structure must be computed by calling factorize_supernodal_symbolic_cholesky on a matrix with the same symbolic structure otherwise, the behavior is unspecified and panics may occur
