[, n] = size(x)
returns the row dimension m and column dimension n
of the matrix x.
function [ok] = size_ok()
ok = true;
x = [ 1 2 3 ; 4 5 6 ];

[m, n] = size(x);
% ----------------
ok = ok & (m == 2);
ok = ok & (n == 3);
return
= x.size1()
n = x.size2()
where x is a ublas matrix<double> and
m, n are size_t objects.
