I am searching for a possiblity to calculate Modified Besselfunctions of imaginary (and non-integer!) order (with a real argument). Can the mathmore-library be used to do that?
Mathematica can calculate these sort of Besselfunctions. I also found an article about a fortran77 algorithm to calculate them ( arxiv.org/abs/cs/0401008v1 ). But I don’t have any clue on how to use MathMore or/and GSL to get these values …
Thanks for your answer, unfortunately i would need the ones of imaginary order, which seem not to be implemented.
Through extensive ‘google search’ I found a fortran implementation of the functions I need from Gil Gomez Amparo, described in “Algorithm 831: Modified Bessel Functions of Imaginary Orders and Positive Argument” which can be found at … portal.acm.org/citation.cfm?doid=992200.992204
Since I have absolutely no experience with fortran (unfortunately), here my new question:
Any easy way to use this fortran code without the need of implementing an according wrapper on my own?
