scripting - Running Mathematica Notebook files in command mode


The question is, how can I run a .nb file in the kernel mode of Mathematica? I am not an expert in Mathematica, but one of our users who use this program says that in the GUI mode, he selects all the cells (CTRL+A) and then evaluates the notebook (SHIFT+ENTER). However, he wants to run the program in background.


When I test with math < file.nb, the program quickly exits; however, in the GUI mode, the run time is very large actually.


I read other documentation articles about that, but since I am not expert in Mathmatica, I have no idea!


As an example, solve.nb file is an input to the command math -run < solve.nb. The output is also available here.


enter image description here


I have no idea what the output means :|



I simply tried to port the solution to Linux. So I wrote a solve.m file containing


NotebookPauseForEvaluation[nb_] := Module[{},

While[NotebookEvaluatingQ[nb],Pause[1]]];

NotebookEvaluatingQ[nb_]:=Module[{},
SelectionMove[nb,All,Notebook];
Or@@Map["Evaluating"/.#&,Developer`CellInformation[nb]]
];

UsingFrontEnd[
nb = NotebookOpen["/home/mahmood/solve.nb"];
SelectionMove[nb, All, Notebook];

SelectionEvaluate[nb]
NotebookPauseForEvaluation[nb];
NotebookSave[nb];
];

Quit[];

Here is the output of what I see


mahmood@cluster:~$ MathKernel -noprompt -initfile solve.m 
mahmood@cluster:~$ 

LinkConnect::linkc: -- Message text not found -- (LinkObject[7wkjs_shm, 3, 1])
^C
mahmood@cluster:~$

Note that I pressec ^c after several minutes. Also, the is no output file containing th results.



I tried the solution as given by selecting the cells, initialize them and then save the file as .m. I did that on a GUI machine. The saved script file contains


(* ::Package:: *)
a = 3;    
Solve[x^2 + a*x + 1 == 0, x]


As you can see, the last line in the notebook file is not there in the script file. I ran the command and saw


mahmood@cluster:~$ /apps/Mathematica/10.3/SystemFiles/Kernel/Binaries/Linux-x86-64/MathematicaScript -script solve3.m 
mahmood@cluster:~$

Is that all? There is no output file containing the result

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...

What is and isn't a valid variable specification for Manipulate?

I have an expression whose terms have arguments (representing subscripts), like this: myExpr = A[0] + V[1,T] I would like to put it inside a Manipulate to see its value as I move around the parameters. (The goal is eventually to plot it wrt one of the variables inside.) However, Mathematica complains when I set V[1,T] as a manipulated variable: Manipulate[Evaluate[myExpr], {A[0], 0, 1}, {V[1, T], 0, 1}] (*Manipulate::vsform: Manipulate argument {V[1,T],0,1} does not have the correct form for a variable specification. >> *) As a workaround, if I get rid of the symbol T inside the argument, it works fine: Manipulate[ Evaluate[myExpr /. T -> 15], {A[0], 0, 1}, {V[1, 15], 0, 1}] Why this behavior? Can anyone point me to the documentation that says what counts as a valid variable? And is there a way to get Manpiulate to accept an expression with a symbolic argument as a variable? Investigations I've done so far: I tried using variableQ from this answer , but it says V[1...
