### Test Suite

Test Status Code Input and Output
1   Fail
x = [2 6 4 9 -10 3 1 5 -10]; y_correct = 5; assert(isequaln(n_max(x,3),y_correct))

Array indices must be positive integers or logical values. Error in n_max (line 6) y = y(x); Error in Test1 (line 3) assert(isequaln(n_max(x,3),y_correct))

2   Pass
x = [2 6 4 9 -10 3 1 5 -10]; y_correct = NaN; assert(isequaln(n_max(x,13),y_correct))

3   Fail
x = [0 0 0 -2 0 -6]; y_correct = -2; assert(isequaln(n_max(x,5),y_correct))

Array indices must be positive integers or logical values. Error in n_max (line 6) y = y(x); Error in Test3 (line 3) assert(isequaln(n_max(x,5),y_correct))

4   Fail
x = [1 1 1 1 1 1]; y_correct = 1; assert(isequaln(n_max(x,4),y_correct))

Assertion failed.

5   Pass
x = [1 1 1 1 1 1]; y_correct = NaN; assert(isequaln(n_max(x,14),y_correct))
