| Description: | returns the inverse of a Poisson-distribution function for elements of an up to 8 dimensional array. |
| Usage: | y = qpois(x,lambda) | |
| Input: | ||
| x | d1 x ... x dm array, the probabilities (0 <= x <= 1) | |
| lambda | scalar, parameter of Poisson distribution (0 < lambda) | |
| Output: | ||
| y | d1 x ... x dm array, quantiles of the Poisson distribution | |
