J0INT
Name:
Type:
Purpose:
This program computes the integral of the Bessel function
J0(x).
Description:
The J0INT function is defined as:
with J0 denoting the Bessel function of the
first kind of order 0.
Dataplot computes this function using ACM Algorithm 757 (see
Reference: below). The function is computed using Chebyshev
expansions, the coefficients of which are given to 20 decimal
places.
Syntax:
LET <y> = J0INT(<x>)
<SUBSET/EXCEPT/FOR qualification>
where <x> is a non-negative number, variable or
parameter;
<y> is a variable or a parameter (depending on what
<x> is) where the computed J0INT function
values are stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
LET A = J0INT(2.3)
PLOT J0INT(X) FOR X = 0 .01 10
LET X2 = J0INT(X1) FOR X1 = 0.1 0.1 3.0
