raylstat

Rayleigh mean and variance

Syntax

[M,V] = raylstat(B)

[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 $b \sqrt{π / 2}$ and the variance is

$\frac{4 - π}{2} b^{2}$

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