size

Array dimensions

C++ Prototype

mwArray size(const mwArray &X, const mwArray &dim=mwArray::DIN);

mwArray size(mwVarargout varargout,
              const mwArray &X,
              const mwArray &dim=mwArray::DIN);

int size(int *cols, const mwArray &array);

C++ Syntax

#include "matlab.hpp"

mwArray X, dim;             // Input argument(s)
mwArray n;                  // Output argument(s) 
mwArray d1, d2, ..., dn;    // Output argument(s) 
mwArray d, m;               // Return value

int i;                      // Return value
int j;                      // Output argument(s) 

d = size(X);
size(mwVarargout(m,n),X);
m = size(X,dim);
size(mwVarargout(d1, d2, ..., dn), X);// X has n dimensions
i = size(&j,X);    // An efficient version of size(X,dim);

MATLAB Syntax

d = size(X)
[m,n] = size(X)
m = size(X,dim)
[d1,d2,...,dn] = size(X)
