I'm doing numerical evaluation of second kind Appell Hypergeometric
Function with two variables.
Reference link: http://mathworld.wolfram.com/AppellHypergeometricFunction.html
First kind Appell Hypergeometric Function with two variables is
implemented as AppellF1 in Mathemetica.
Is there any implementation of second kind Appell Hypergeometric
Function with two variables in any math software package? The brute
force implementation in Matlab often overflows.
Thanks for your input!
