The Struve functions are defined in Abramowitz and Stegun, Handbook of Mathematical Functions, A&S Chapter 12 and (DLMF 11). The Struve Function \({\bf H}_{\nu}(z)\) is a particular solution of the differential equation:
which has the general soution
The Struve Function H of order \(\nu\) and argument \(z\):
(A&S eqn 12.1.3) and (DLMF 11.2.E1).
When besselexpand
is true
, struve_h
is expanded in terms
of elementary functions when the order \(v\) is half of an odd integer.

The Modified Struve Function L of order \(\nu\) and argument \(z\):
(A&S eqn 12.2.1) and (DLMF 11.2.E2).
When besselexpand
is true
, struve_l
is expanded in terms
of elementary functions when the order \(v\) is half of an odd integer.
