从终端/ JAVA在MATLAB改变目录 [英] Change Directory in MATLAB from Terminal/JAVA

问题描述

我需要能够改变MATLAB的工作目录不与命令窗口交互。我是从一个Java应用程序启动MATLAB。现在唯一的解决办法我已经拿出正在关闭MATLAB，从Java改变目录，并重新发动。有没有从Java发送MATLAB的CD命令的一些简化的方法吗？在命令行这样做也将工作，因为我可以用getRuntime（）。EXEC（命令）

I need to be able to change the working directory in MATLAB without interacting with the command window. I'm launching MATLAB from a Java application. Right now the only solution I've come up with is closing MATLAB, changing directory from JAVA and relaunching. Is there some streamlined way to send MATLAB the 'cd' command from JAVA? Doing so from the command-line would also work, since I could use getRuntime().exec(command)

谢谢！

推荐答案

您可以如果你使用同一个JVM Matlab的（如果没有的话我也没办法）做到这一点使用JMI。这里是不是这么多的在线信息（它的 WAY 的无证/不支持）。谷歌或阅读这样的： http://www.cs.virginia.edu/怀特豪斯〜/ MATLAB / JavaMatlab.html 。总之，你需要包括Matlab的相关JAR文件，然后使用com.mathworks.jmi.Matlab的功能。例如：

You can do this using JMI if you're using the same JVM as Matlab (if not then I have no idea). There is not much online info about this (it's WAY undocumented/unsupported). Google it or read this: http://www.cs.virginia.edu/~whitehouse/matlab/JavaMatlab.html. In short, you need to include Matlab's relevant JAR file and then use com.mathworks.jmi.Matlab's functionality. For example:

Matlab.evalConsoleOutput（CD（'C：\\ Program Files文件\\'））;
