chfact - sparse Cholesky factorization

Calling Sequence

spcho=chfact(A)

Parameters

• A : square symmetric positive sparse matrix
• spcho : list containing the Cholesky factors in coded form

Description

spcho=chfact(A) computes the sparse Cholesky factors of sparse matrix A , assumed symmetric positive definite. This function is based on the Ng-Peyton programs (ORNL). See the Fortran programs for a complete description of the variables in spcho . This function is to be used with chsolve .
