Function Reference: poissinv

statistics: x = poissinv (p, lambda)

Inverse of the Poisson cumulative distribution function (iCDF).

For each element of p, compute the quantile (the inverse of the CDF) at p of the Poisson distribution with parameter lambda. The size of p is the common size of x and lambda. A scalar input functions as a constant matrix of the same size as the other inputs.
