Hi Ralf Das ist "cool". Da ich das Gegenstück dazu habe
https://github.com/nilqed/spadlib/tree/master/mmaparse können die "MMA Fans" (ich bin keiner ;-) FriCAS auch benutzen :) Ich wollte den Parser einmal für Rubi->Fricas benutzen, aber das war mir dann doch zuviel Arbeit, um all die MMA Funktionen zu übersetzen. Vielleicht versuche ich es nochmals, falls mir langweilig wird, Beste Grüsse Kurt On Fri, 14 Mar 2025 at 00:14, 'Ralf Hemmecke' via FriCAS - computer algebra system <fricas-devel@googlegroups.com> wrote: > > I sometimes want to compare FriCAS output with that what Mathematica > returns and also wanted to be able to cut&paste FriCAS expressions to > Mathematica without always having the need to change the syntax > manually.
