### Test Suite

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 = 0.0067 t_myrepmat = 1.3000e-05 ```

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 = 9.6000e-05 t_myrepmat = 1.0000e-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)

``` t_repmat = 5.9000e-04 t_myrepmat = 9.0000e-06 ```
