I just sent an email to your email address listed in your forum profile. Let me know if the attached project works out in your case.

The Fortran 2008 standard only specifies that these intrinsics be provided for REAL arguments currently. However, I believe the SLATEC library provides this functionality. I should have a version compiled for Simply Fortran that I can provide you via email to get you up and running. I'll test it out tomorrow morning and get the library to you.

Complex arguments to Bessel functions?

2013-01-23T23:31:16Z

Hi all,

I'm using simply fortran for a university project and have run into a slight issue; I'm using the intrinsic Bessel function (BESSEL_JN) in my code which have thus far been inputting real arguments. However I now need to feed complex arguments to the function but the intrinsic function will only accept real arguments.

Is there a way to include or add a Bessel function into the library which can handle complexes? Or any other solutions?

Thanks
