ANSI C code for bessel functions

[punit_p]

Hello,

I am looking for an ANSI C implementation for a bessel function of the 1st order. Does anyone know a source where I can obtain this from?

Thanks,

The bessj1 routine (if you're referring to the 1st-order Bessel function of the first kind) in the "Numerical Recipes in C" book should work fine.
