我需要帮助通过MatlabControl在 Java 和 MATLAB 之间进行连接。
首先我想在演练中测试代码，但每次我遇到同样的异常：
myfunc.m：
function myfunc()
disp('hello from MYFUNC')
end
爪哇：
class ShowImage {
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('E:\\vm')");
proxy.feval("myfunc");
proxy.eval("rmpath('E:\\vm)");
// close connection
proxy.disconnect();
}}
这里有例外：
Exception in thread "main" matlabcontrol.MatlabConnectionException: Could not launch MATLAB. Command: [matlab, -r, javaaddpath 'C:\Users\walaa\Desktop\matlabcontrol-4.0.0.jar'; matlabcontrol.MatlabClassLoaderHelper.configureClassLoading(); javarmpath 'C:\Users\walaa\Desktop\matlabcontrol-4.0.0.jar'; matlabcontrol.MatlabConnector.connectFromMatlab('PROXY_RECEIVER_42dd44d9-815e-41ad-bec9-e469718b5710', 2100);]

我不知道是什么问题，任何帮助将不胜感激！
