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

$P=[1$:$5]\text{'}.*2$;

$P=$cusum$($P$)/$sum$($P$)$;

The output of the histogram is supposed to have the original random vector and another vectore almost identical, but i dont know how that works.
