# raylstat

Rayleigh mean and variance

## Syntax

[M,V] = raylstat(B)

## Description

[M,V] = raylstat(B) returns the mean of and variance for the Rayleigh distribution with scale parameter B.

The mean of the Rayleigh distribution with parameter b is $b\sqrt{\pi /2}$and the variance is

$\frac{4-\pi }{2}{b}^{2}$

## Examples

```[mn,v] = raylstat(1)
mn =
1.2533
v =
0.4292```
