Fast Matlab Code for hypergeometric function $_2F_1$ I am looking for a good numerical algorithm to evaluate the hypergeometric function $_2F_1$ in Matlab (hypergeom in Matlab is very slow). I looked across the Internet, but did not find anything useful. Does anybody here have an idea where to find a fast algorithm to compute this function?

There is Matlab source code for J. Pearson's master's thesis "Computation of Hypergeometric Functions". The thesis is a available as 
http://people.maths.ox.ac.uk/porterm/research/pearson_final.pdf
and the Matlab code URL is http://people.maths.ox.ac.uk/porterm/research/hypergeometricpackage.zip (I cannot judge the code because I am working with Pascal/Delphi).
