Test Status Code Input and Output
1   Pass
x=[1 2]; y=1; y_correct=[1 2]; assert(isequal(muldif(x,y),y_correct));

2   Pass
x=1; y=1; y_correct=1; assert(isequal(muldif(x,y),y_correct));

3   Fail
x=[1 2 0 1]; y=[8 5 1]; y_correct = [8 21 11 10 5 1]; assert(isequal(muldif(x,y),y_correct))

Error using * Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'. Error in muldif (line 2) result = (x*y); Error in Test3 (line 4) assert(isequal(muldif(x,y),y_correct))
