Hello all, I need to evaluate Kummer's confluent hypergeometric function for a purely imaginary argument:
1F1(a, b; ix) where i is the imaginary unit, a, b, x are real, and a, b > 0. From what I gather GSL only allows computing 1F1(a,b; x) with real arguments. However there is a version of 2F1 that admits complex arguments. Is there a reason for this omission? Any suggestions on how I can compute 1F1(a, b; ix)? Thanks in advance. Best, cossio --------------------------------------------------- [http://5.cim.co.cu/cim.gif]
