Ouput value manupulation?

I have got different values ​​from a certain calculation,

Where x = (0.5, 0.70, -0.81, -0.90)

I want to get read of the minus values ​​and replace with '0', I am doing like-

x (3) = 0; % x (3) is the position of the value in the specific column

x (4) = 0; % x (4) is the position of the value in the specific column

Now I am having x = (0.5, 0.70, 0, 0)

So, my question is there any other possible way do that? i, e with functions or limits

x_new = x.*(x > 0);

or

x_new = x;
x_new(x_new <= 0) = 0;

or

xnew = max(x,0);
