statistics: p = poisscdf (x, lambda)
statistics: p = poisscdf (x, lambda, "upper")

Poisson cumulative distribution function (CDF).

For each element of x, compute the cumulative distribution function (CDF) at x 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.

p = poisscdf (x, x, lambda, "upper") computes the upper tail probability of the lognormal distribution.
