urd

          urd(x)     (no rate restriction)

Description

Where the argument in parentheses is a function table number. urd generates random values according to a discrete random distribution contained in function table x. The user creates the discrete distribution histogram table by using GEN41. To create the table, the user must define an arbitrary amount of number pairs. The first number of each pair represents a value and the second represents its probability. See GEN41 for more details.

urd can also be used to generate values following a set of ranges of probabilities by using distribution functions generated by GEN42. In order to simulate continuous ranges, the table designated by x should be reasonably large, since urd does not interpolate between table elements.

urd is the same as duserrnd, but as a function, urd may be used in any other expression. See duserrnd for more information.
