Test Status Code Input and Output
1   Pass
%% x = [0 1 2 3 4]; assert(isequal(mono_increase(x),true));

2   Fail
%% x = [0]; assert(isequal(mono_increase(x),true));

Error: Output argument "tf" (and maybe others) not assigned during call to "/users/msssytem8/mono_increase.m>mono_increase".

3   Pass
%% x = [0 0 0 0 0]; assert(isequal(mono_increase(x),false));

i = 5 tf = 0 i = 5 tf = 0 i = 5 tf = 0 i = 5 tf = 0

4   Pass
%% x = [0 1 2 3 -4]; assert(isequal(mono_increase(x),false));

i = 5 tf = 0

5   Fail
%% x = [-3 -4 2 3 4]; assert(isequal(mono_increase(x),false));

Error: Assertion failed.

6   Pass
