**Block Category:** Random Generator

**Description:** The rayleigh block generates random
numbers for a Rayleigh distribution. It usually arises when a two-dimensional
vector (for example, wind
velocity)
has its two orthogonal components normally
and independently distributed. The absolute value will have a Rayleigh
distribution. The distribution may also arise in the case of random complex
numbers whose real and imaginary components are normally and independently
distributed. The absolute value of these numbers will then be
Rayleigh-distributed. For more information, see http://en.wikipedia.org/wiki/Rayleigh_distribution

**Label:** Indicates a user-defined block label that appears when

**Mode:** Specifies the mode of the curve. You can also
enter a value in hexadecimal notation or
as a C
expression.
