### Test Suite

Test Status Code Input and Output
1   Fail
x = 1.7; m = 197; n = 535; tic y_correct = repmat(x, m, n); t_repmat = toc tic y_myrepmat = my_repmat(x, m, n); t_myrepmat = toc assert(isequal(y_myrepmat,y_correct) && t_myrepmat < t_repmat/2)

t_repmat = 6.5900e-04 t_myrepmat = 0.0052

Assertion failed.

2   Fail
x = -0.3; m = 1; n = 5350; tic y_correct = repmat(x, m, n); t_repmat = toc tic y_myrepmat = my_repmat(x, m, n); t_myrepmat = toc assert(isequal(y_myrepmat,y_correct) && t_myrepmat < t_repmat/2)

t_repmat = 2.0500e-04 t_myrepmat = 4.4200e-04
