Linear system of equations? Maybe expressing it in matrix form could help. A 21x21 matrix certainly fits even in a small monitor.
Everything inside the Manipulate gets re-evaluated on every update, but a large part of what you have there is constant, like the vector constant, the plot[1], ... plot[8]. My advice is to move out of the Manipulate body as much as...
A long time ago, out of the blue, my father purchased me a copy of Mathematica 2.2 for students during a Mac World Expo in Boston. I never asked for it, he just purchased it for me and I had not idea of what to do with it. At the time I preferred to...
Here is another way: mainList /. {n_Integer?(CurryApplied[2][MemberQ][listRed]) :> Style[n, Red], n_Integer?(CurryApplied[2][MemberQ][listBlue]) :> Style[n, Blue]}
This is how I do it. First define this function to that you can apply or insert a color with a single button: colorPasteButton = Button[" ", ib := InputNotebook[]; If[NotebookRead[ib] === {}, Paste[ib, #], ...
Not sure if this will help, but you mentioned "the database I'm querying is remote". In case the bandwidth of your connection is the bottleneck, it might be possible to activate compression so that the connection may work faster. When creating ssh...
Hello Yvan, I think the issue is that you need to store the result of the import into a variable that is shown somewhere else and wrapped inside a Dynamic[]. For example: DynamicModule[{result = "please load file"}, {Dynamic[result], ...
How about this: data = {90, 89, 88, 87, 86, 86, 85, 84, 84, 83, 82, 81, 81, 80, 80, 79, 78, 78}; Show[ Plot[{91 - n + Floor[(n - 1)/4]}, {n, 1, 10}], ListPlot[data]] ![enter image description here][1] [1]:...
Are you saving to a network drive or a local drive? I have noticed corrupt notebooks are very rare when saving to a local drive (at least under Windows). By the way, take a look at ...
