(errno )

is too large and the function returns zero.

Notes

struve_h0 evaluates an approximation to the Struve function of order zero, .

Please consult the NIST Digital Library of Mathematical Functions for a detailed discussion of the Struve function including special cases, transformations, relations and asymptotic approximations.

The approximation method used by this function is based on Chebyshev expansions.
