Purpose

Get and set the sparse ir and jc arrays.

C Synopsis

int *mxGetIr(pm)
  Matrix *pm;
void mxSetIr(pm,ir)
  Matrix *pm;
  int *ir;
int *mxGetJc(pm)
  Matrix *pm;
void mxSetJc(pm,jc)
  Matrix *pm;
  int *jc;

Fortran Synopsis

integer*4 function mxGetIr(pm)
integer*4 function mxGetJc(pm)
subroutine mxSetIr(pm,ir)
subroutine mxSetJc(pm,jc)
integer*4 pm,ir,jc

Arguments

ir
pointer to the ir array
jc
pointer to the jc array
pm
pointer to the Matrix structure

Description

These routines let you get and set the pointers to the ir and jc arrays associated with sparse Matrices.

If the Matrix is full, mxGetIr and mxGetJc return NULL.
