front end - How do I create annotations for functions?


In 10.3, Mathematica starts captioning symbol-names into foreign languages if your Interface preferences are set to have Mathematica in a foreign language.


Graph annotated


I poked around the Attributes, and viewed the Cell expression, but from the code I couldn't find any sign that this was happening at all (though it's obviously happening somehow).



I want to be able to make this happen on my own functions: to be able to supply translations, for instance, or extremely short inline explanations. For example, if I made a little function toInt, I might want to attach a type annotation String->Integer. This could help offset the verbosity of Mathematica code by making the notebook interface that little bit more intelligent.


One can see the translations available using WolframLanguageData:


WolframLanguageData[Graph][
 EntityProperty["WolframLanguageSymbol", "Translations"]
]

How does Mathematica do the translation annotations, and how can I do it myself?



Answer




Karsten 7. suggested a better method in the comments, which does not require a modification of any system files and can be used under English language setting. It works on my 10.2 installation after applying the following procedures:





  1. Under the user's directory (FileNameJoin[{$UserBaseDirectory,"SystemFiles\\FrontEnd\\SystemResources\\FunctionalFrequency"}]), add a file named, say, CustomAnnotation.m.




  2. Edit this CustomAnnotation.m as you want, consisting with the format of the built-in language specification file as described in my old answer (see below).




  3. Either open the Option Inspector and add the following path to Global Options â–º File Locations â–º PrivatePaths â–º "TranslationData":




    FrontEnd`FileName[{$UserBaseDirectory, "SystemFiles", "FrontEnd", "SystemResources", "FunctionalFrequency"}]

    or execute the following code within the notebook:


    CurrentValue[$FrontEnd, {PrivatePaths, "TranslationData"}] = 
     Append[CurrentValue[$FrontEnd, {PrivatePaths, "TranslationData"}], 
       FrontEnd`FileName[{$UserBaseDirectory, "SystemFiles", "FrontEnd", 
         "SystemResources", "FunctionalFrequency"}]];


  4. Restart Mathematica.





  5. Execute the following code in Mathematica (replace $FrontEnd with $FrontEndSession for non-persistent modification):


    SetOptions[$FrontEnd, TranslationOptions -> {"Enabled" -> True, 
                                                 "Language" -> "CustomAnnotation"}]




NOTE:




  1. The following method works on my Mathematica 10.2, but not tested on other versions. [Also tested on Mathematica 10.3, Mac OS 10.11.1.]

  2. The following method involving modification of a system file, thus is likely prohibited by the EULA.





  1. First find the language specific file located on a path similar to the following (I will use the simplified Chinese as a demonstration):



    C:\Program Files\Wolfram Research\Mathematica\10.2\SystemFiles\FrontEnd\SystemResources\FunctionalFrequency\ChineseSimplified.m






  2. Add a new function annotation line (the 3rd line in the snapshot):


    Mathematica graphics




  3. Open Mathematica with language setting to simplified Chinese, type ThisIsATestFunction in a notebook:


    Mathematica graphics

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...

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...

plotting - Plot 4D data with color as 4th dimension

I have a list of 4D data (x position, y position, amplitude, wavelength). I want to plot x, y, and amplitude on a 3D plot and have the color of the points correspond to the wavelength. I have seen many examples using functions to define color but my wavelength cannot be expressed by an analytic function. Is there a simple way to do this? Answer Here a another possible way to visualize 4D data: data = Flatten[Table[{x, y, x^2 + y^2, Sin[x - y]}, {x, -Pi, Pi,Pi/10}, {y,-Pi,Pi, Pi/10}], 1]; You can use the function Point along with VertexColors . Now the points are places using the first three elements and the color is determined by the fourth. In this case I used Hue, but you can use whatever you prefer. Graphics3D[ Point[data[[All, 1 ;; 3]], VertexColors -> Hue /@ data[[All, 4]]], Axes -> True, BoxRatios -> {1, 1, 1/GoldenRatio}]
