graphics - How to speed up TextJustification in Mathematica 10


Based on this question: - Version 7 print environment - I set up two 10 page test documents in version 7.0.1 and version 10.1. The version 7 document exported to PDF in 4.18 seconds whereas the version 10 export took 424.6 seconds.


Can I speed up export from version 10?


These are the test exports.


For Version 7


time = DateList[];
SetOptions[$FrontEndSession,

  PrintingOptions -> {"PrintingMargins" -> {{45, 43}, {17, 31}},
    "FirstPageHeader" -> False, "FirstPageFooter" -> False,
    "RestPagesHeader" -> False, "RestPagesFooter" -> False,
    "Magnification" -> 1}];
text = StringReplace[StringTake[
    ExampleData[{"Text", "Prufrock"}], 4221],
   FromCharacterCode[{195, 162, 128, 194, 153}] -> "'"];
square = Graphics[{Orange, Rectangle[{0, 0}, {70, 70}]},
   PlotRange -> {{0, 70}, {0, 70}}];
column = Table[Inset[square, {415, 100 i}, {Left, Bottom},

    {70, 70}], {i, 0, 9}];
page = Graphics[{White, Rectangle[{0, 0}, {500, 973}], Black,
    Inset[TextCell[text, LineSpacing -> {0, 16},
      TextJustification -> 1], {0, 973}, {Left, Top}, {400, 973}],
    column}, PlotRange -> {{0, 500}, {0, 973}}, ImageSize -> 500, 
   BaseStyle -> {FontFamily -> "Times", FontWeight -> "Plain", FontSize -> 14}];
nb = CreateDocument[ConstantArray[ExpressionCell[page, "Print"], 10],
   WindowSize -> 800];
filename = StringJoin["v", ToString[Round@$VersionNumber], ".pdf"];
Quiet@DeleteFile[filename];

Export[filename, nb];
NotebookClose[nb];
DateDifference[time, DateList[], "Second"]


{4.18004, Second}



For Version 10


time = DateList[];
SetOptions[$FrontEndSession,

  PrintingOptions -> {"PrintingMargins" -> {{11, 43}, {15, 31}},
    "FirstPageHeader" -> False, "FirstPageFooter" -> False,
    "RestPagesHeader" -> False, "RestPagesFooter" -> False,
    "Magnification" -> 1}];
text = StringReplace[StringTake[
    ExampleData[{"Text", "Prufrock"}], 4221],
   FromCharacterCode[{195, 162, 128, 194, 153}] -> "'"];
square = Graphics[{Orange, Rectangle[{0, 0}, {70, 70}]},
   PlotRange -> {{0, 70}, {0, 70}}];
column = Table[Inset[square, {415, 100 i}, {Left, Bottom},

    {70, 70}], {i, 0, 9}];
page = Graphics[{White, Rectangle[{0, 0}, {500, 973}], Black,
    Inset[TextCell[text, LineSpacing -> {0, 17},
      TextJustification -> 1], {0, 973}, {Left, Top}, {400, 973}],
    column}, PlotRange -> {{0, 500}, {0, 973}}, ImageSize -> 555,
   BaseStyle -> {FontFamily -> "Times", FontWeight -> "Plain", FontSize -> 15.5}];
nb = CreateDocument[ConstantArray[ExpressionCell[page, "Print"], 10],
   WindowSize -> 800];
filename = StringJoin["v", ToString[Round@$VersionNumber], ".pdf"];
Quiet@DeleteFile[filename];

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

How to thread a list

mathematical optimization - Minimizing using indices, error: Part::pkspec1: The expression cannot be used as a part specification

I want to use Minimize where the variables to minimize are indices pointing into an array. Here a MWE that hopefully shows what my problem is. vars = u@# & /@ Range[3]; cons = Flatten@ { Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; Minimize[{Total@((vec1[[#]] - vec2[[u[#]]])^2 & /@ Range[1, 3]), cons}, vars, Integers] The error I get: Part::pkspec1: The expression u[1] cannot be used as a part specification. >> Answer Ok, it seems that one can get around Mathematica trying to evaluate vec2[[u[1]]] too early by using the function Indexed[vec2,u[1]] . The working MWE would then look like the following: vars = u@# & /@ Range[3]; cons = Flatten@{ Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; NMinimize[ {Total@((vec1[[#]] - Indexed[vec2, u[#]])^2 & /@ R...
