Bessell numeric functions

[marcelino]

I need to count compound formulation which consists BESSEL numeric functions (Bessel Function J0(x), J1(x), Jn(x), Y0(x), Y1(x), Yn(x)).Do I need some special library? Or are there some special commands, functions? Thanks for help in advance.

Bessel function source code can be found in "Numerical Recipes In C" by Press, Flannery, Teukolsky, and Vetterling. There is a web site with links to purchasable code downloads, book sources, and other material at:

It includes links to two sites that host .PDF versions of the book including the code for the various functions. This is an excellent reference for the example code plus general concepts and methods for numerical computing.

Thanks for helping hand but how can I be sure that book which cost 65$ will really help me? I even cannot see what does this book consist. Are there any other solutions?

The book text and graphics including source code are in .pdf form at:

http://library.lanl.gov/numerical/bookcpdf.html

You can read the book and try the code without purchasing the book or the cd.

Thanks very much. I hope I could cope with it now. It would be nice if math.h without any problems would count Bessell numeric functions.
