Expand description

Computes the numeric values of the Cholesky Bunch-Kaufman factors of the matrix A with intranodal pivoting, and stores them in L_values.

§Note

Only the lower (not upper, unlikely the other functions) triangular part of A is accessed.

§Panics

The symbolic structure must be computed by calling factorize_supernodal_symbolic on a matrix with the same symbolic structure. Otherwise, the behavior is unspecified and panics may occur.
