MATLAB: How to get com.mathworks.engine.* package

Question

Here is my code

 import com.mathworks.engine.*;
 import java.util.Arrays;
 public class javaPutVar {
    public static void main(String[] args) throws Exception {
        MatlabEngine eng = MatlabEngine.startMatlab();
        eng.putVariable("x", 7.0);
        eng.putVariable("y", 3.0);
        eng.eval("z = complex(x, y);");
        String[] w = eng.feval("who");
        System.out.println("MATLAB workspace variables " + Arrays.toString(w));
        eng.close();
    }
}

This code is showing error:

 javaPutVar.java:1: error: package com.mathworks.engine does not exist
 import com.mathworks.engine.*;
^
javaPutVar.java:6: error: cannot find symbol
        MatlabEngine eng = MatlabEngine.startMatlab();
        ^
  symbol:   class MatlabEngine
  location: class javaPutVar
javaPutVar.java:6: error: cannot find symbol
        MatlabEngine eng = MatlabEngine.startMatlab();
                           ^
  symbol:   variable MatlabEngine
  location: class javaPutVar
3 errors

How can I fix this errors? How can I get com.mathworks.engine.* package ?

Answer 1

Are you using release R2016b or later? According to the documentation and the Release Notes that's when this functionality was introduced.
