This class provides an interface between the Java language and MATLAB, enabling you to evaluate MATLAB functions and expressions from Java. Constructor Summary The MatlabEngine class provides static methods to start MATLAB and to connect to a shared MATLAB session synchronously or asynchronously. Only these static methods can instantiate this class: • Start MATLAB synchronously — “startMatlab” on page 1-4 • Connect to shared MATLAB session synchronously — “connectMatlab” on page 1-7 • Start MATLAB asynchronously — “startMatlabAsync” on page 1-5 • Connect to shared MATLAB session asynchronously — “connectMatlabAsync” on page 1-8 Unsupported Startup Options The engine does not support these MATLAB startup options: • -h • -help • -? • -n 1-2 com.mathworks.engine.MatlabEngine class • -e • -softwareopengl • -logfile For information on MATLAB startup options, see “Commonly Used Startup Options”. Method Summary Static Methods “startMatlab” on Start MATLAB synchronously. page 1-4 “startMatlabAsyncS”tart MATLAB asynchronously. on page 1-5 “findMatlab” on Find all available shared MATLAB sessions from a local machine page 1-6 synchronously. “findMatlabAsync”Find all available shared MATLAB sessions from a local machine on page 1-6 asynchronously. “connectMatlab” Connect to a shared MATLAB session on a local machine on page 1-7 synchronously. “connectMatlabAsyCncon”nect to a shared MATLAB session on a local machine on page 1-8 asynchronously.
