I need to generate n random varibales with Beta Distribution with specified mean, variance, meninmum and maximum limit. I would be thankful if you can help me.

I have problem with determinig the alfa and beta parameters, how is possible to determine these paramaters??

You write you want to generate random numbers with specified mean and variance.

Mean and variance are functions of alpha and beta:

https://en.wikipedia.org/wiki/Beta_distribution

So solve these relations E[X]=f(alpha,beta), Var[X]=g(alpha,beta) for alpha and beta.

The difficulty with the above is that Wikipedia only deals with the case of x ~ [0, 1] or x ~ (0,1) rather than a more generalized range.
