NAG[g05eyc] NAG[nag_return_discrete] - Pseudo-random integer from reference vector
|
|
Calling Sequence
g05eyc(r)
nag_return_discrete(. . .)
Parameters
|
|
r - float;
|
|
|
|
On entry: the reference vector for which memory has been allocated by a previous call to another g05 function. To free this memory the macro NAG_FREE should be added in the users' program after the final call to nag_return_discrete (g05eyc).

Description

|
|
Purpose
|
|
nag_return_discrete (g05eyc) returns a pseudo-random integer taken from a discrete distribution defined by a reference vector r.
|
|
|
Description
|
|
nag_return_discrete (g05eyc) is designed for use in conjunction with other functions in this chapter, which set up the reference vector r for specific distributions or according to a distribution specified in terms of the PDF (probability density function) or CDF (cumulative distribution function). See the g05 Chapter Introduction.
The function generates a random number  from g05cac (nag_random_continuous_uniform) and searches the CDF in r for the smallest value  such that CDF and CDF .
