 Jul 1 comment How to change the position of the PlotLabel? also: 1 and 2 Jun 19 comment How to save the current configuration of preferences? If you are on windows, I think the preference is in C:\Users\[your_user_name]\AppData\Roaming\Mathematica\FrontEnd\init.m Jun 1 comment plotting sine of a wiener process and calculating derivative FWIW, data = RandomFunction[WienerProcess[.3, .5], {0, 1, 0.01}]; g[{a_, b_}] := {a, Sin[b]}; ds = Flatten[Normal[data], 1]; dg = Table[{i*.01, (ds[[i + 1, 2]] - ds[[i, 2]])/.01}, {i, 1, 100}]; ListLinePlot[g /@ ds] ListLinePlot[dg] Jun 1 comment ContourPlot has weird Jagged line maybe just let the code with big PlotPoints run for several hours? ContourPlot[ p == q (1 + (2 (1 + 3 (p - q)^2) (.1))/(1 - (p - q)^2)^3), {p, -3, 3}, {q, -3, 3}, PlotPoints -> 600, PlotRange -> All, Exclusions -> True] gives smooth result in my testing. You can also try playing with MaxRecursion a bit. May 27 comment Update/refresh notebook variable color on clear Works like a charm for me :-) Thanks! (tested on Mathematica ver. 10.0.2.0 on windows) May 27 accepted Update/refresh notebook variable color on clear May 27 asked Update/refresh notebook variable color on clear May 19 comment plot randomly oriented lines Do you want the the planes to be discrete,for example random integer zs? Because with float random numbers of @LLlAMnYP 's comment, it's highly, highly unlikely that two lines will end up in the same plane.

Mar 24 awarded Yearling Mar 24 comment How to find out where an error occurs? @Szabolcs Thanks for the tip! Mar 24 comment How to find out where an error occurs? Try the built-in debugger: Evaluation>Debugger with Break at messages checked. Mar 24 answered How to find out where an error occurs? Mar 23 answered Delete data were y = “NS” in a list with elements {x, y} Mar 23 comment How could I add the WorldMap skin to this parametricPlot3d? also the example here Mar 23 comment How could I add the WorldMap skin to this parametricPlot3d? refer to this post Mar 23 comment Is there a bug in MatrixExp in Mathematica v10? Confirmed the issue in ver.10. For your example specifically, since the matrix can be exactly diagonalized using Eigensystem, you can get a nice analytic expression--I'm assuming it's used in quantum mechanics where the matrix is the Hamiltonian (easily diagonalized in your example) and you want the unitary propagator with MatrixExp.
