Test Status Code Input and Output
1   Fail
x = [1 2 3; 4 5 6]; y_correct = [-3,-3,-3;0,0,0]; assert(isequal(normalize(x),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 normalize (line 2) x-max(x,1)*ones(size(x,1),1); Error in Test1 (line 3) assert(isequal(normalize(x),y_correct))

2   Fail
x=[1; 2; 3] y_correct = [-2;-1;0]; assert(isequal(normalize(x),y_correct))

x = 1 2 3
