# raylpdf

## PURPOSE

% Compute the probability density function of the Rayleigh distribution.

## SYNOPSIS

function y = raylpdf (x, sigma)

## DESCRIPTION

```% -*- texinfo -*-
% @deftypefn {Function File} {@var{y} =} raylpdf (@var{x}, @var{sigma})
% Compute the probability density function of the Rayleigh distribution.
%
%
% @itemize @bullet
% @item
% @var{x} is the support. The elements of @var{x} must be non-negative.
%
% @item
% @var{sigma} is the parameter of the Rayleigh distribution. The elements
% of @var{sigma} must be positive.
% @end itemize
% @var{x} and @var{sigma} must be of common size or one of them must be
% scalar.
%
%
% @itemize @bullet
% @item
% @var{y} is the probability density of the Rayleigh distribution at each
% element of @var{x} and corresponding parameter @var{sigma}.
% @end itemize
%
%
% @example
% @group
% x = 0:0.5:2.5;
% sigma = 1:6;
% y = raylpdf (x, sigma)
