Replace the random bit generator in the previous assignment with an integer source that generates numbers from $1$ to $N$ where the probability of getting the outcome $x[n]=i$ is equal to $P_{-}$i taken from a vector that is user generated. So in your script, create $P=[P_{-}1,P_{-}2,$dots,$P_{-}N]$ and use this in your circuit. After you run your circuit, generate a histogram that should match this vector. To test your code, try setting $P$ as follows:

$\%$ let the user specify how the source probabilities as a vector $P=[1$:$5]{!}^{{?}^{{?}^{?}}}2$;

$P=$cum${\displaystyle \underset{?}{\overset{?}{}}}\frac{P}{?}$ sum $(P)$;
