poisscdf

Cumulative distribution function (CDF) for Poisson distribution

Usage

poisscdf(x, lambda)

• The input arrays lambda and x should have compatible sizes. They contain, respectively, mean values of the CDFs being evaluated, and x values at which the CDFs are evaluated.
• x and lambda must contain real numbers only.
• If lambda and x have different but compatible sizes, one of the inputs will be expanded to match the size of the other input.
