Pass Variables from MATLAB to Java
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.
Coordinate Conversion
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();
}
