programming - Deploying Mathematica Content Online


I have the following program at home, which draws on a batch of pre-processed files (that are word frequency text files, compiled using ToLowerCase, Tally and Sort. Here is an example of the file that it draws on:


{{"i", 3073}, {"you", 2860}, {"the", 1741}, {"and", 1518}, {"a", 1218}, {"me", 1209}, {"to", 1153}, {"my", 913}, {"t", 855}, {"that", 843}... and so on. Each file is about ~ 50KB, and it's been generated using Put and is thus grabbed using Get.


I use them for the following program, which essentially plots word frequency for a given year (each year has its own file). It's along a similar lines as the Google ngram viewer, but on a very specific historical dataset.



Manipulate[viewerCount1 = {};
 viewerCount2 = {};
 SetDirectory["/users/myNAME/desktop/DB/Put/"];
 filenames = FileNames["*.txt"];
 Do[
  input = Get[file];
  yearLength = Length[input];
  AppendTo[viewerCount1, 
   If[Length[Flatten[Cases[input, {word1, _}]]] == 0, 0, 
     Flatten[Cases[input, {word1, _}]][[2]]]/yearLength];

  AppendTo[viewerCount2, 
   If[Length[Flatten[Cases[input, {word2, _}]]] == 0, 0, 
     Flatten[Cases[input, {word2, _}]][[2]]]/yearLength];
  , {file, filenames}];
 DateListPlot[{Tooltip[viewerCount1, word1], 
   Tooltip[viewerCount2, word2]}, {1964}, Joined -> True, 
  PlotLabel -> "Number of Total Word Appearances by % of All Words", 
  PlotStyle -> {{Red}, {Blue}}], {{word1, "war", 
   "First Word (Red)"}}, {{word2, "peace", "Second Word (Blue)"}}]


enter image description here


Here's the crux of the question, however. Is there a good way to deploy this online so other people can access it? I assume this is too big for the CDF format? Alternatively, WebMathematica sounds promising, but before I upgrade my Mathematica purchase I would love to hear if the community thinks that would be useful.


I know that there have been discussions elsewhere about sharing dynamic content with non-Mathematica users, but these seem to not rely on specific external files.


Or, am I using the wrong language to deploy the final version of this?



Answer



You cannot use CDF for this because you have textual import fields and these are not supported when you embed online. You will just get a big grey box. InputField cannot accept strings (non-numeric) for online CDFs unless you are Wolfram Research and can override it. (I'm guessing you don't want to pay many thousands for CDF Pro.)


You also cannot import and export into an online embedded CDF, not even a Pro CDF (got that first hand from Wolfram). This is for security reasons.


So to create something like you have described using Mathematica and have online, the only possible way to do it, it would seem, is to use webMathematica.

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...

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...

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}]
