CATLAN
Name:
Type:
Purpose:
Compute the Catlan beta function.
Description:
The Catlan beta function is defined as:
For better numerical stability, Dataplot actually
computes B(s) - 1.
Dataplot uses a Fortran translation of a C routine
given in "Atlas For Computing Mathematical Functions"
(see the Reference section below).
Syntax:
LET <y> = CATLAN(<x>)
<SUBSET/EXCEPT/FOR qualification>
where <x> is a number, variable, or parameter (> 1);
<y> is a variable or a parameter (depending on what
<x> is) where the computed Catlan beta - 1 values
are stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
LET A = CATLAN(2)
LET A = CATLAN(X)
LET X2 = CATLAN(X) FOR X = 0.1 0.1 3.0
