Calling MATLAB as COM Automation Server

Write COM applications to work with MATLAB®

Automation is a COM protocol that allows one application (the controller or client) to control objects exported by another application (the server). MATLAB supports COM Automation server capabilities on Microsoft® Windows® operating systems. Any Windows program that can be configured as an Automation client can control MATLAB. Some examples are Microsoft Excel® and Microsoft Access™, as well as Microsoft Visual Basic® and Microsoft Visual C++® programs.

To get started writing applications to call MATLAB as a COM Automation server:

If you build client applications using C, C++, or Fortran, then use MATLAB Engine Applications instead of an Automation server. For more information, see Choosing Engine Applications.

To access COM components from MATLAB, see COM Objects in MATLAB.

This example calls MATLAB functions from a Microsoft Visual Basic client application.

Pass Complex Data to MATLAB from C# Client

This example creates complex data in a client C# program and passes it to MATLAB.


Waiting for MATLAB Application to Complete

When you call a MATLAB function from another program, the program might display a timeout message while waiting for the MATLAB function to complete.
