Hi everyone,
Is it possible to generate non-integer Poisson random numbers? The poissrnd function appears to generate integer random numbers only …
Thank you!!

I am not sure why you have three parameters rather than 1. See https://en.wikipedia.org/wiki/Poisson_distribution
In your code, you might want to use element wise operators, and use exp
function f = poisson (k, lambda) f = (lambda.^k) .* exp(-lambda) ./ factorial(k)doc normcdfdoc normpdfWhen you know what you want but not sure the name, try something like
