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.
