Abstract
AbstractThis chapter focuses on the symbolic phase of a sparse Cholesky solver. The sparsity pattern
$$\mathcal {S}\{A\}$$
S
{
A
}
of the symmetric positive definite (SPD) matrix A is used to determine the nonzero structure of the Cholesky factor L without computing the numerical values of the nonzeros.
