2   Pass
x = orth(randn(4)); y_correct = true; assert(isequal(isOrthogonal(x),y_correct))

m = 1

3   Pass
x = orth(randn(5)); y_correct = true; assert(isequal(isOrthogonal(x),y_correct))

m = 1.0000

4   Pass
x=sqrt([3,1;1,1]); y_correct = false; assert(isequal(isOrthogonal(x),y_correct))

m = 0.7321

5   Pass
