Usage REAL Beta,X,Y
Y=FNP_rayleigh(Beta,X)
Description
FNP_rayleigh returns the value of the integral of the Rayleigh probability density function of parameter Beta (here written as β), at x, P(x;). P is defined by the expression
which reduces to
P is defined for all positive values of .
P(x;)
Errors
|
FNP_rayleigh causes an HTBasic error if its arguments are not all of type REAL or if the value of is negative or zero.
