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));

Index exceeds the number of array elements (1). Error in mono_increase (line 6) if x(k+1) > x(k); Error in Test2 (line 2) assert(isequal(mono_increase(x),true));

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

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