function a = tests(n)
a = ones(n);
a(2:2:numel(a)) = 0;
Any ideas why this only works on matreices with an odd number of rows/columns? On the even matrices it changes entire rows to 0's or 1's
the ones and zeroes should be alternate whatever their position be. In even columns/rows the element a(1,1) and a(1,2) both remain the same i.e. 1 and 1 so it doesn't work for even number of columns\rows.
