RBETA

rbeta

Random numbers from the beta distribution (inversion method)

         x = rbeta(n,a,b)
	Input	n	positive integer or a vector [lig,col] of 2 
			positive integers
		a,b	positive reals 
	Output	x 	n-vector or a n-matrix of random numbers 
			chosen from a beta distribution with parameters 
			a and b (density :
			x--> x.^(a-1) .* (1-x).^(b-1) ./ beta(a,b)1_{0<x<1}
