### Test Suite

Test Status Code Input and Output
1   Fail
a = [1 2 3 4 5]; b = [2 3 4 5 6]; y_correct = [1 6]; assert(isequal(vector_diff(a,b),y_correct))

y = 1 6

Assertion failed.

2   Fail
a = 10:-2:0; b = 1:2:11; y_correct = 0:11; assert(isequal(vector_diff(a,b),y_correct))

y = 0 1 2 3 4 5 6 7 8 9 10 11

Assertion failed.

3   Fail
a=magic(5); b=magic(6); y_correct = 26:36; assert(isequal(vector_diff(a,b),y_correct))

Error using horzcat Dimensions of arrays being concatenated are not consistent. Error in vector_diff (line 2) y = setdiff([a(:) b(:)],intersect(a(:),b(:))) Error in Test3 (line 4) assert(isequal(vector_diff(a,b),y_correct))

4   Fail

Error using horzcat Dimensions of arrays being concatenated are not consistent. Error in vector_diff (line 2) y = setdiff([a(:) b(:)],intersect(a(:),b(:))) Error in Test4 (line 4) assert(isequal(vector_diff(a,b),y_correct))

5   Fail

Assertion failed.

6   Fail
