Test Status Code Input and Output
1   Fail
x=[2 5]; y=[5 6]; z=[5 7]; y_correct = [ 50 210]; assert(isequal(vec_mul(x,y,z),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 vec_mul (line 2) r = x*y*z; Error in Test1 (line 5) assert(isequal(vec_mul(x,y,z),y_correct))

2   Fail
x = [1 1 1 ]; y=[1 1 1 ]; z=[1 1 1]; y_correct = [1 1 1]; assert(isequal(vec_mul(x,y,z),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.
