binoinv
              Inverse of the Binomial cumulative distribution function (iCDF).
For each element of p, compute the quantile (the inverse of the CDF) of the binomial distribution with parameters n and ps, where n is the number of trials and ps is the probability of success. The size of x is the common size of p, n, and ps. A scalar input functions as a constant matrix of the same size as the other inputs.
