How can I get com.mathworks.engine.* package ?
显示 更早的评论
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 ?

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

You should already have it. Have you performed the setup steps necessary to get started using the API?
- Open the documentation in your installation using the doc command.
- In the documentation for MATLAB, click on "Advanced Software Development".
- On the "Advanced Software Development" page click on "MATLAB API for Other Languages".
- On the "MATLAB API for Other Languages" page click on "MATLAB Engine API for Java".
- On the "MATLAB Engine API for Java" page click on "Build Java Engine Programs" in the Getting Started section of the Topics.
- Follow the steps under the General Requirements section and then read the section for the operating system you're using.
