kernel - Autoload a package


I want to aoutoload a package at the beginning of a notebook. I set up my directory as written here


How to use the Autoload directory?


So, I have these files:



../Work/MyFile.nb


../Work/Autoload/MyPack/MyPack.m


../Work/Autoload/MyPack/Kernel/init.m.




MyPack.m :


ClearAll["Progetto`*"];  

BeginPackage[ "Progetto`"]

Prova::usage="Prova[]"

Begin["`Private`"];

Prova[]:=5+1;


End[]

EndPackage[]

init.m:


 Get["MyPack`MyPack`"]

In MyFile.nb, I would like use Prova[], but the output isn't 6 but is Prova[].


Where am I wrong? Am I missing something in init.m?

In this case, create an initialization cell in the notebook, and load that package in that cell. Select the cell, and tick Cell menu -> Cell Properties -> Initialization Cell.


"Autoloading" refers to loading something on kernel startup, and is completely independent of notebooks. This is not what you need.



So, I have these files:



../Work/MyFile.nb



../Work/Autoload/MyPack/MyPack.m




The Autoload directory I wrote about in the answer you are linking to is located in $UserBaseDirectory. There is only one* such directory, and it is used on kernel startup. It does not interact with notebooks in any way.


* To be completely accurate, there are a few, but they all live in fixed locations, such as $UserBaseDirectory, $BaseDirectory, $InstallationDirectory/SystemFiles, etc.

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-...

plotting - Magnifying Glass on a Plot

Although there is a trick in TEX magnifying glass but I want to know is there any function to magnifying glass on a plot with Mathematica ? For example for a function as Sin[x] and at x=Pi/6 Below, this is just a picture desired from the cited site. the image got huge unfortunately I don't know how can I change the size of an image here! Answer Insetting a magnified part of the original Plot A) by adding a new Plot of the specified range xPos = Pi/6; range = 0.2; f = Sin; xyMinMax = {{xPos - range, xPos + range}, {f[xPos] - range*GoldenRatio^-1, f[xPos] + range*GoldenRatio^-1}}; Plot[f[x], {x, 0, 5}, Epilog -> {Transparent, EdgeForm[Thick], Rectangle[Sequence @@ Transpose[xyMinMax]], Inset[Plot[f[x], {x, xPos - range, xPos + range}, Frame -> True, Axes -> False, PlotRange -> xyMinMax, ImageSize -> 270], {4., 0.5}]}, ImageSize -> 700] B) by adding a new Plot within a Circle mf = RegionMember[Disk[{xPos, f[xPos]}, {range, range/GoldenRatio}]] Show...
