### Function Reference: `raylpdf`

statistics: y = raylpdf (x, sigma)

Rayleigh probability density function (PDF).

For each element of x, compute the probability density function (PDF) of the Rayleigh distribution with scale parameter sigma. The size of p is the common size of x 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

### Example: 1

     ## Plot various PDFs from the Rayleigh distribution
     x = 0:0.01:10;
     y1 = raylpdf (x, 0.5);
     y2 = raylpdf (x, 1);
     y3 = raylpdf (x, 2);
     y4 = raylpdf (x, 3);
     y5 = raylpdf (x, 4);
     plot (x, y1, "-b", x, y2, "g", x, y3, "-r", x, y4, "-m", x, y5, "-k")
     grid on
     ylim ([0, 1.25])
