raylpdf

Rayleigh probability density function

Syntax

Y = raylpdf(X,B)

Description

Y = raylpdf(X,B) computes the Rayleigh pdf at each of the values in X using the corresponding scale parameter, B. X and B can be vectors, matrices, or multidimensional arrays that all have the same size, which is also the size of Y. A scalar input for X or B is expanded to a constant array with the same dimensions as the other input.

The Rayleigh pdf is

y=f(x|b)=xb2e(x22b2)

Examples

collapse all

Compute the pdf of a Rayleigh distribution with parameter B = 0.5.

x = [0:0.01:2];
p = raylpdf(x,0.5);

Plot the pdf.

figure;
plot(x,p)
