mxIsFull, mxIsSparse

Purpose

Inquire sparsity of a Matrix.

C Synopsis

int mxIsFull(pm)
  Matrix *pm;
int mxIsSparse(pm)
  Matrix *pm;

Fortran Synopsis

integer*4 function mxIsFull(pm)
integer*4 function mxIsSparse(pm)
integer*4 pm

Arguments

pm
pointer to Matrix structure

Description

These routines let you determine if a Matrix is stored in full or sparse form.

mxIsFull returns 1 if the Matrix pointed to by pm is a full Matrix and 0 otherwise.

mxIsSparse returns 1 if the Matrix pointed to by pm is a sparse Matrix and 0 otherwise.

There are no corresponding set routines. Use mxCreateSparse to create sparse Matrices.
