Bessel implementation in C++

[smus]

library c++ bessel

Hi There,

I am a MS degree student and want to implement the integer indexed Bessel function values in C++. I search through some books about this topic but every formula gives me different values. Which formula must I use.

Thanks for your help.
Regards

Heard about "GSL"? It's the GNU Scientific Library, which is a numerical library for C and C++ programmers. Do a google search and you'll get what you need.

Yeah i know about this library and Numerical Recepies in C++ but all of them gives another value if you mean GSL gives the best approximation about values u right, so i understand that i must use GSL.

Thanks for your interest.
