### Test Suite

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

tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0

Assertion failed.

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

Output argument "tf" (and maybe others) not assigned during call to "mono_increase". Error in Test2 (line 2) assert(isequal(mono_increase(x),true));

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

tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0

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

tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 1

Assertion failed.

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

tf = logical 1 tf = logical 0 tf = logical 0 tf = logical 0

6   Fail
x = 1:.1:10; assert(isequal(mono_increase(x),true));

tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0 tf = logical 0
