in the test suite, test number 3 tests for vector [0 0 0 0 0] if it is monotically increasing, but in the assertion it claims it is false, meaning it is not monotically increasing, which i dont think is true.
the assertion should check it as true.
this is from wikipedia:
[ A function is called monotonically increasing if for all x and y such that x <=f(y) ]
the (issorted) function should be enough to check for monotically increasing.

Test	Status	Code Input and Output
1	Pass	x = [0 1 2 3 4]; assert(isequal(mono_increase(x),true));
2	Pass	x = [0]; assert(isequal(mono_increase(x),true));
3	Pass	x = [0 0 0 0 0]; assert(isequal(mono_increase(x),false));
4	Pass	x = [0 1 2 3 -4]; assert(isequal(mono_increase(x),false));
5	Pass	x = [-3 -4 2 3 4]; assert(isequal(mono_increase(x),false));
6	Pass	x = 1:.1:10; assert(isequal(mono_increase(x),true));
7	Pass	x = cumsum(rand(1,100)); x(5) = -1; assert(isequal(mono_increase(x),false));
8	Pass	x = cumsum(rand(1,50)); assert(isequal(mono_increase(x),true));
