complex number operation in udf?
 

I want to use the complex number operation in udf, but udf has no this type of operation. Can I define the operation in it? and how? By the way, the operation inludes complex Bessel function. Thanks for your help.

If you use compiled UDF, you can just use a C/C++ library which manages complex numbers.

There are many open sources solutions. For example, you could consider GSL.

You can find information on the GNU Scientific Library here:

If you work on Linux, you probably just have to install it from the CD's of your distribution.
