Extract and create sparse band and diagonal matrices

C++ Prototype

mwArray spdiags(const mwArray &in1, 
                const mwArray &in2=mwArray::DIN, 
                const mwArray &in3=mwArray::DIN, 
                const mwArray &in4=mwArray::DIN);

mwArray spdiags(mwArray *out1, 
                const mwArray &in1);

C++ Syntax

#include "matlab.hpp"

mwArray m, n;
mwArray A, B, d;

B = spdiags(&d,A);
B = spdiags(A,d);
A = spdiags(B,d,A);
A = spdiags(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)
