Expand description

computes the row indices and numeric values of the cholesky $LDL^H$ factor of the matrix $A$, and stores them in l_row_idx and l_values

§note

only the upper triangular part of $A$ is accessed

§panics

the elimination tree and column counts must be computed by calling prefactorize_symbolic_cholesky with the same matrix, then the column pointers are computed from a prefix sum of the column counts. otherwise, the behavior is unspecified and panics may occur
