Test Status Code Input and Output
1   Fail

Index exceeds the number of array elements (5). Error in mono_increase (line 3) if (x(i) < x(i+1)) Error in Test1 (line 2) 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 3) if (x(i) < x(i+1)) Error in Test2 (line 2) assert(isequal(mono_increase(x),true));

3   Pass
