これで私を助けてください!javaからmatlabcontrolを使用してmatlab関数を呼び出そうとすると、システムが指定されたファイルを見つけることができなかったことが通知されます。
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();
}
}
私が得るエラーは以下の通りです。
