### Test Suite

Test Status Code Input and Output
1   Pass
x = 1; y_correct = 1; assert(isequal(rainbow(x),y_correct))

a = 1 y = 1

2   Fail
x = 3; y_correct = [1 2 3; 2 3 2; 3 2 1]; assert(isequal(rainbow(x),y_correct))

a = 1 2 3 y = 1 2 3 a = 0×1 empty double column vector y = 1 2 3 a = 0×1 empty double column vector y = 1 2 3

Assertion failed.

3   Fail
x = 5; y_correct = [1 2 3 4 5; 2 3 4 5 4; 3 4 5 4 3; 4 5 4 3 2; 5 4 3 2 1]; assert(isequal(rainbow(x),y_correct))

a = 1 2 3 4 5 y = 1 2 3 4 5 a = 0×1 empty double column vector y = 1 2 3 4 5

Index in position 2 exceeds array bounds (must not exceed 1). Error in rainbow (line 5) a = a([2:end],x-k) Error in Test3 (line 3) assert(isequal(rainbow(x),y_correct))

4   Fail

a = 1 2 3 4 5 6 7 y = 1 2 3 4 5 6 7 a = 0×1 empty double column vector y = 1 2 3 4 5 6 7

Index in position 2 exceeds array bounds (must not exceed 1). Error in rainbow (line 5) a = a([2:end],x-k) Error in Test4 (line 10) assert(isequal(rainbow(x),y_correct))
