where z is a complex number with a positive real component,
Dataplot computes this function using the CPSI routines from "Computation of Special Functions" (see the References section below).
where <xr> is a variable, number, or parameter containing positive values; <xc> is a variable, number, or parameter; positive values; <yr> is a variable or a parameter (depending on what <xr> and <xc> are) where the computed psi values are stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional. This syntax computes the real component of the complex psi function. The <xr> and <xc> values are the real and complex components of the input argument respectively.
