Computes the supernodal 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 simplicial::prefactorize_symbolic_cholesky with the same matrix. Otherwise, the behavior is unspecified and panics may occur.
