### Test Suite

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

x = -10 -10 1 2 3 4 5 6 9 y = 5

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

x = -10 -10 1 2 3 4 5 6 9

Array indices must be positive integers or logical values. Error in n_max (line 3) y = x(length(x) - n + 1) Error in Test2 (line 3) assert(isequaln(n_max(x,13),y_correct))

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

x = -6 -2 0 0 0 0 y = -2

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

x = 1 1 1 1 1 1 y = 1

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

x = 1 1 1 1 1 1

Array indices must be positive integers or logical values. Error in n_max (line 3) y = x(length(x) - n + 1) Error in Test5 (line 3) assert(isequaln(n_max(x,14),y_correct))
