chfact            Scilab Group            Scilab Function            chfact
NAME
   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.
