Function Reference: raylinv

statistics: x = raylinv (p, sigma)

Inverse of the Rayleigh cumulative distribution function (iCDF).

For each element of p, compute the quantile (the inverse of the CDF) of the Rayleigh distribution with scale parameter sigma. The size of x is the common size of p and sigma. A scalar input functions as a constant matrix of the same size as the other inputs.

Further information about the Rayleigh distribution can be found at https://en.wikipedia.org/wiki/Rayleigh_distribution

 ## Plot various iCDFs from the Rayleigh distribution

 x1 = raylinv (p, 0.5);
 x2 = raylinv (p, 1);
 x3 = raylinv (p, 2);
 x4 = raylinv (p, 3);
 x5 = raylinv (p, 4);
 plot (p, x1, "-b", p, x2, "g", p, x3, "-r", p, x4, "-m", p, x5, "-k")
