with I0 denoting the modified 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.
<y> is a variable or a parameter (depending on what <x> is) where the computed I0INT function values are stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
