REXP

rexpweib
Random numbers from the exponential or weibull distributions

         x=rexpweib(n,l)
       Input    n  positive integer or vector [lig,col] of integers
                l  positive real
                a  Weibull parameter (default a=1: exponential dist.)

       Output   x  n-vector of random numbers
                   chosen from a weibull distribution 
                            ( F(x) = 1-exp-[(l*x)^a]  )
