Abstract:
We consider the approximation of the modified Struve functions ${{\mathbf {L}}_0}$ and ${{\mathbf {L}}_1}$, and the related functions ${I_0} - {{\mathbf {L}}_0}$ and ${I_1} - {{\mathbf {L}}_1}$, where ${I_0},{I_1}$ are modified Bessel functions. Chebyshev expansions are derived to an accuracy of 20D for these functions. By using generalized bilinear and biquadratic maps we optimize the number of coefficients for 20D accuracy.References
