Use the MatlabEngine getVariable or getVariableAsync methods
to get variables from the MATLAB® base workspace. To determine
the appropriate mapping of MATLAB type to Java® type, see Java Data Type Conversions.
This example code uses the MATLAB cart2sph function
to convert from Cartesian to spherical coordinates. The getVariable method
gets the returned spherical coordinate variables from the MATLAB base
workspace.
import com.mathworks.engine.*;
public class GetPolar {
public static void main(String[] args) throws Exception {
MatlabEngine eng = MatlabEngine.startMatlab();
eng.eval("[az,el,r] = cart2sph(5, 7, 3);");
double az = eng.getVariable("az");
double el = eng.getVariable("el");
double r = eng.getVariable("r");
System.out.println("Azimuth: " + az);
System.out.println("Elevation: " + el);
System.out.println("Radius " + r);
eng.close();
}
