Java调用simulink

5.把simulink文件（.mdl或.slx）复制到java工程，这里以txt.slx为例，位置如下：

import com.mathworks.engine.*;
import java.util.concurrent.Future;
import java.util.Arrays;

public class RunSimulation {
    public static void main(String[] args) throws Exception {
        MatlabEngine eng = MatlabEngine.startMatlab();
        Future<Void>  fLoad = eng.evalAsync("load_system('txt')");
        while (!fLoad.isDone()){
            System.out.println("Loading Simulink model...");
            Thread.sleep(10000);
        }
        Future<Void> fSim = eng.evalAsync("simOut = sim('txt','SaveOutput'," +
                "'on','OutputSaveName','yOut'," +
                "'SaveTime','on','TimeSaveName','tOut');");
        while (!fSim.isDone()) {
            System.out.println("Running Simulation...");
            Thread.sleep(10000);
        }
        // Get simulation data
        eng.eval("y = simOut.get('yOut');");
        eng.eval("t = simOut.get('tOut');");
        // Graph results and create image file
        eng.eval("plot(t,y)");
        eng.eval("print('vdpPlot','-djpeg')");
        // Return results to Java
        double[][] y = eng.getVariable("y");
        double[] t = eng.getVariable("t");
        // Display results
        System.out.println("Simulation result " + Arrays.deepToString(y));
        System.out.println("Time vector " + Arrays.toString(t));
        eng.close();
    }
}
