### Test Suite

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

tf = logical 1

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

Assertion failed.

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

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

Output argument "tf" (and maybe others) not assigned during call to "mono_increase". Error in Test4 (line 2) assert(isequal(mono_increase(x),false));

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

Output argument "tf" (and maybe others) not assigned during call to "mono_increase". Error in Test5 (line 2) assert(isequal(mono_increase(x),false));

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

tf = logical 1

7   Fail
x = cumsum(rand(1,100)); x(5) = -1; assert(isequal(mono_increase(x),false));

Output argument "tf" (and maybe others) not assigned during call to "mono_increase". Error in Test7 (line 3) assert(isequal(mono_increase(x),false));

8   Pass
x = cumsum(rand(1,50)); assert(isequal(mono_increase(x),true));

tf = logical 1
