Source 
pub fn factorize_simplicial_symbolic_cholesky<I: Index>(
    A: SymbolicSparseColMatRef<'_, I>,

Expand description

computes the symbolic structure of the cholesky factor of the matrix $A$

§note

only the upper triangular part of $A$ is analyzed

§panics

the elimination tree and column counts must be computed by calling prefactorize_symbolic_cholesky with the same matrix. otherwise, the behavior is unspecified and panics may occur
