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
