Function factorize_simplicial_numeric_ldlt

pub fn factorize_simplicial_numeric_ldlt<I, E>(

    A: SparseColMatRef<'_, I, E>,

Expand description

Computes the numeric values of the Cholesky LDLT factors of the matrix A, and stores them in L_values.

§Note

Only the upper triangular part of A is accessed.

§Panics

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