C Prototype

mxArray *mlfSpdiags(mxArray **res2,
                    mxArray *arg1, 
                    mxArray *arg2,
                    mxArray *arg3,
                    mxArray *arg4);

C Syntax

#include "matlab.h"

mxArray *A;                 
mxArray *d, *m, *n;         
mxArray *B = NULL, *A = NULL;

mlfAssign(&B, mlfSpdiags(&d,A,NULL,NULL,NULL));
mlfAssign(&B, mlfSpdiags(NULL,A,d,NULL,NULL));
mlfAssign(&A, mlfSpdiags(NULL,B,d,A,NULL));
mlfAssign(&A, mlfSpdiags(NULL,B,d,m,n));

MATLAB Syntax

[B,d] = spdiags(A)
B = spdiags(A,d)
A = spdiags(B,d,A)
A = spdiags(B,d,m,n)
