naginterfaces.library.specfun.struve_h0(x)

struve_h0 returns the value of the Struve function of order $0$, $H_0\left(x\right)$.

For full information please refer to the NAG Library document for s17ga

Parameters

xfloat

The argument $x$ of the function.

Returns

h0float

The value of the function at $x$.

Raises

NagValueError

(errno $1$)

$x$ is too large and the function returns zero.

Notes

struve_h0 evaluates an approximation to the Struve function of order zero, $H_0\left(x\right)$.

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.
