Question

请帮帮我吧！当我尝试使用java中的matlabcontrol调用我的matlab函数时，它告诉我系统找不到指定的文件。

package matcontro;

import matlabcontrol.*;

public class HelloWorld

 {

      public static void main(String[] args) throws MatlabConnectionException, MatlabInvocationException
     {
         // create proxy
         MatlabProxyFactoryOptions options = new MatlabProxyFactoryOptions.Builder()
                 .setUsePreviouslyControlledSession(true)
                 .build();
         MatlabProxyFactory factory = new MatlabProxyFactory(options);
        MatlabProxy proxy = factory.getProxy(); 

         // call builtin function
         proxy.eval("disp('hello world')");

         // call user-defined function (must be on the path)
         proxy.eval("addpath('C:\\ Users\\HASENDE\\My Documents\\MATLAB')");
         proxy.feval("myfunc");
         proxy.eval("rmpath('C:\\ Users\\HASENDE\\My Documents\\MATLAB')");

         // close connection
         proxy.disconnect();
     }
 }

我得到的错误如下;

运行：

Exception in thread "main" matlabcontrol.MatlabConnectionException: Could not launch MATLAB. Command: [matlab, -r, javaaddpath 'C:\Users\HASENDE\Documents\NetBeansProjects\Java Classpath Libraries\matlabcontrol-4.0.0.jar'; matlabcontrol.MatlabClassLoaderHelper.configureClassLoading(); javarmpath 'C:\Users\HASENDE\Documents\NetBeansProjects\Java Classpath Libraries\matlabcontrol-4.0.0.jar'; matlabcontrol.MatlabConnector.connectFromMatlab('PROXY_RECEIVER_01caa56d-9ed7-4e39-a45b-345051024d49', 2100);]

使用matlabcontrol从netbeans调用matlab
