double v, x, y, struve();
y = struve(v, x);
Computes the Struve function Hv(x) of order v, argument x. Negative x is rejected unless v is an integer.
This module also contains the hypergeometric functions 1F2 and 3F0, and a routine for the Bessel function Yv(x) with noninteger v.
Not accurately characterized, but spot checked against tables.
