.SH NAME
chfact - sparse Cholesky factorization
.SH CALLING SEQUENCE
.nf
spcho=chfact(A)
.fi
.SH PARAMETERS
.TP
A
: square symmetric positive sparse matrix
.TP 
spcho
: list containing the Cholesky factors in coded form
.SH DESCRIPTION
\fVspcho=chfact(A)\fR computes the sparse Cholesky factors of sparse
matrix \fVA\fR, 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
\fVspcho\fR. This function is to be used with \fVchsolve\fR.
