I was trying to connect Matlab with Java using the Matlab Engine, I followed the examples of this web page: https://www.mathworks.com/help/matlab/matlab_external/execute-matlab-functions-from-java.html?requestedDomain=www.mathworks.com
After adding the requiered references and writting down this code:
import com.mathworks.engine.*;
public class CNN
{
public static void main(String[] args) throws Exception{
MatlabEngine eng = MatlabEngine.startMatlab();
double[] a = {2.0 ,4.0, 6.0};
double[] roots = eng.feval("sqrt", a);
eng.close();
}
}
Eclipse shows an error on feval function
It seems that I am using wrong arguments on the feval function. But I am using the code posted on the reference page of mathworks.
All the other example codes do not compile.
what am I doing wrong ? if the documentation is wrong how can I know how to use this function?

This looks like an Eclipse issue. The example code should just compile if you ignore the hints.
