Test Status Code Input and Output
1   Pass
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 = 5.9000e-04 t_myrepmat = 1.4700e-04

2   Pass
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 = 1.8200e-04 t_myrepmat = 8.8000e-05

3   Pass
x = 0; m = 14; 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)
