Description Beta distribution random number generator (positive values only). This is an x-class noise generator. Syntax ares betarand krange, kalpha, kbeta ires betarand krange, kalpha, kbeta kres betarand krange, kalpha, kbeta Performance krange -- range of the random numbers (0 - krange). kalpha -- alpha value. If kalpha is smaller than one, smaller values favor values near 0. kbeta -- beta value. If kbeta is smaller than one, smaller values favor values near krange. If both kalpha and kbeta equal one we have uniform distribution. If both kalpha and kbeta are greater than one we have a sort of Gaussian distribution. Outputs only positive numbers. For more detailed explanation of these distributions, see: C. Dodge - T.A. Jerse 1985. Computer music. Schirmer books. pp.265 - 286 D. Lorrain. A panoply of stochastic cannons. In C. Roads, ed. 1989.

See the sections Real-time Audio and Command Line Flags for more information on using command line flags. Its output should include a line like: instr 1: i1 = 24583.412 See Also seed, bexprnd, cauchy, exprand, gauss, linrand, pcauchy, poisson, trirand, unirand, weibull Credits Author: &nameparis; MIT, Cambridge 1995 Existed in 3.30 Example written by &namekevin;.
