I have seen the ChangeLog entry about that.

Given that the algorithm is highly recursive this can easily be the case. I remember some information that systems like Mathematica only apply it as the final try to get a result but use simpler techniques first. > One can try Gruntz using 'mrv_limit' command > (need package qualification because by default the > MrvLimitPackage is not exposed). > > I would like to include recognition of Fresnel > integral in the pattern matching integrator. > Raoul, do you have some newer version?

I think you merged commit 899191cbb4ee34612b0fd41914902f787067e3d3 from my "split_function" branch. (But not the Bessel stuff which is unfinished and broken.) I'll rebase my branches tomorrow. -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
