Hello, I'm surprised that in the lyx-1.2.0 announcement, there's no mention of "math-extern" function in the newly added features.
I have been using "math-extern" with Maple nearly everyday for several months and it becomes quite stable in current lyx-1.2.0. You can integrate, differentiate, simplify, factorize,.... within mathed. What it cannot do is to define functions and to load extra packages. So solving differential equations within mathed is not possible at the moment, but eventually will be done, Right, Andre Poenitz? I think with this newly added feature, lyx is now competing with "WorkPlace" in real sense. Any comments? --cghan
