 Jul 28 comment solving non-linear set of equations using NSolve in order to get all roots Just to clarify: You want to solve for t and phip? Jul 7 awarded Nice Answer Mar 8 comment FindMinimum's WorkingPrecision behaviour Great. Thanks for the additional info! Mar 8 accepted FindMinimum's WorkingPrecision behaviour Mar 2 asked FindMinimum's WorkingPrecision behaviour Feb 2 awarded Yearling Dec 3 comment Is Replace doing double work? Totally blind guess and probably wrong, but I could imagine this is connected to how Mathematica determines if an expression changed (i.e., when to stop computing)... Dec 3 comment Is Replace doing double work? Replace does a depth-first postorder traversal of the expression tree. See this very interesting thread for a discussion of the topic. Dec 2 awarded Nice Answer Nov 20 comment Why does LyapunovSolve solve non-standard form? I agree that this is a little strange, as with this definition Q will normally not be positive definite. Also, RiccatiSolve solves the form corresponding to what you call "standard form". But why is this important for you? Sep 30 awarded Explainer Sep 24 awarded Autobiographer Aug 21 comment Integral converging in M9 but not in M10 I can't reproduce your problem with ParallelTable. On the other hand I don't understand the significance of Quit here. In what order should I evaluate which commands? Can you elaborate pls? Aug 21 comment V10 interface problems I'm on Linux and I've been experiencing (1) for many versions and still do, so I'm pretty much used to it. I think it's a problem with the graphics toolkit they are using. For me the text field is restored when I click into the general area where it's supposed to be. I can also confirm (3), but again, I've had that problem in earlier versions. Aug 20 comment Why isn't Lookup treated like other symbols? You seem to misunderstand what ´TempHead /: Lookup[t1_TempHead, t2_TempHead]´ actually does (which caused some confusion for RunnyKine and m_goldberg, see below): It adds a definition to (the UpValues) of ´TempHead´, not to ´Lookup´. That's why unprotecting ´Lookup´ doesn't help of course. Aug 20 comment Integral converging in M9 but not in M10 Of course it can, you are changing the state of your Mathematica session after all. I would suggest that you go through your code step by step and see which symbols/expressions evaluate to something unexpected. Start from the bottom and work your way up. I don't think, however, that someone will do this work for you. Aug 20 comment Integral converging in M9 but not in M10 @Zet I can confirm Michael's observation that this code gives the desired result on V9 and V10 (on Linux, but it's very unlikely this makes a difference) Aug 20 comment Integral converging in M9 but not in M10 @Zet Did you restart your kernel? Aug 20 comment Algebraic expressions on pure functions Just curious, why are you making the postfix/prefix distinction? Aug 17 comment A problem about generating [] automatically Not an answer to the original question, but you can change keybindings as described here
