### 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)

Error: Output argument "y" (and maybe others) not assigned during call to "/users/msssystem6/my_repmat.m>my_repmat".

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)

Error: Output argument "y" (and maybe others) not assigned during call to "/users/msssystem6/my_repmat.m>my_repmat".

3   Fail
%% 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)

Error: Output argument "y" (and maybe others) not assigned during call to "/users/msssystem6/my_repmat.m>my_repmat".
