I have been trying to write this formula in matlab, but I have not had many results. The formula is as follows:
in addition, the Ln must have a conditional, where, if Pi is negative or equal to 0, the result of the ln of that Pi is 0.
If someone can help me, it would be very helpful
Thanks

W = log(p);
W(p <= 0) = 0;
N = exp(-sum( p .* W));
