如何用Java创建Mathematica Notebook? [英] How to create a Mathematica Notebook in Java?

问题描述

我正在寻找创建Mathematica Notebook文件的原型"Hello World"程序.

I am looking for the prototypical 'Hello World' program that creates a Mathematica Notebook file.

我有这个工作程序.

 package graphica;

 import com.wolfram.jlink.*;

 /**
  *
  * @author Nilo
  */
public class MathematicaTester {

public static void main(String[] args) {

    KernelLink ml = null; 
    String jLinkDir = "C:\\Program Files\\Wolfram Research\\Mathematica\\8.0\\SystemFiles\\Links\\JLink";
    System.setProperty("com.wolfram.jlink.libdir", jLinkDir);

    try { 
        ml = MathLinkFactory.createKernelLink("-linkmode launch -linkname 'C:\\Program Files\\Wolfram Research\\Mathematica\\8.0\\MathKernel.exe'");

        ml.discardAnswer();
        String expr = "Sum[k^2,{k,1,11}]";
        ml.evaluate(expr);
        ml.waitForAnswer();
        String x = ml.getString();
        System.out.println("Result = " + x);

    } catch (MathLinkException e) { 
        System.out.println("Fatal error opening link: " + 
        e.getMessage()); 
        return; 
    }
}
}

运行此命令时，将得到以下-expected-输出.

When I run this I get the following -expected- output.

运行:
结果= 506
建立成功(总时间:2秒)

run:
Result = 506
BUILD SUCCESSFUL (total time: 2 seconds)

问题:

我想更改此程序，以便创建Mathematica笔记本.该程序将(最终)在一行mma命令字符串之后添加一行.如果同时启动Mathematica前端，并且可以通过Java程序的请求对mma代码进行评估，那就太好了.至关重要的是创建一个笔记本，以后可以通过mma前端打开.

I want to change this program so that a Mathematica Notebook is created. The program will ( eventually ) add line after line of mma command strings. It would be nice if a Mathematica frontend is started at the same time and that the mma code is evaluated by request from the Java program. Essential is the creation of a Notebook that can be opened later by the mma front-end.

推荐答案

进行了一些研究，但我自己回答了这个问题.

It took some research but I managed to answer the question myself.

 package graphica;

 import com.wolfram.jlink.*;

 /**
  *
  * @author Nilo
  */
 public class MathematicaTester {

     public static void main(String[] args) {

         KernelLink ml = null; 
         String jLinkDir = "C:\\Program Files\\Wolfram Research\\Mathematica\\8.0\    \SystemFiles\\Links\\JLink";
         System.setProperty("com.wolfram.jlink.libdir", jLinkDir);

         try { 
             ml = MathLinkFactory.createKernelLink("-linkmode launch -linkname 'C:\\Program Files\\Wolfram Research\\Mathematica\\8.0\\MathKernel.exe'");
        //test-1
             ml.discardAnswer();
             String expr = "Sum[k,{k,1,11}]";
             ml.evaluate(expr);
             ml.waitForAnswer();
             String x = ml.getString();
             System.out.println("Result = " + x);
       //test-2
             expr = "UsingFrontEnd[nb=NotebookPut[Notebook[{Cell[\"Graphics3D[Cuboid[]]\", \"Input\"]}]]]";
             System.out.println("Result = " + ml.evaluateToOutputForm(expr, 40) );
             expr = "UsingFrontEnd[NotebookSave[nb,\"TERRANOVA1\"]]";
             System.out.println("Result = " + ml.evaluateToOutputForm(expr, 40) );

         } catch (MathLinkException e) { 
             System.out.println("Fatal error opening link: " + 
             e.getMessage()); 
             return; 
         }
     }
 }
