Create sparse matrix

C Prototype

mxArray *mlfSparse(mxArray *i, mxArray *j, mxArray *s, 
                   mxArray *m, mxArray *n, mxArray *nzmax);

C Syntax

#include "matlab.h"

mxArray *A, *i;                 /* Required input argument(s) */
mxArray *j, *s, *m, *n, *nzmax; /* Optional input argument(s) */
mxArray *S = NULL;              /* Return value */

mlfAssign(&S, mlfSparse(A,NULL,NULL,NULL,NULL,NULL));
mlfAssign(&S, mlfSparse(i,j,s,m,n,nzmax));
mlfAssign(&S, mlfSparse(i,j,s,m,n,NULL));
mlfAssign(&S, mlfSparse(i,j,s,NULL,NULL,NULL));
mlfAssign(&S, mlfSparse(m,n,NULL,NULL,NULL,NULL));

MATLAB Syntax

S = sparse(A)
S = sparse(i,j,s,m,n,nzmax)
S = sparse(i,j,s,m,n)
S = sparse(i,j,s)
S = sparse(m,n)
