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