Sine integral Si(x)

[1-10] /10 | Disp-Num |

- Purpose of use
- Retired physicist looking for code to generate table of dipole antenna complex impedance as function of wavelength and antenna length. This was a step along the way.
- Comment/Request
- Would like code to incorporate in more complicated function evaluation. Fortran or Basic preferred, C, C++ or Java OK too.
