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 controller can control MATLAB. Some examples are Microsoft Excel® and Microsoft Access™, and many Microsoft Visual Basic® and Microsoft Visual C++® programs.
If you build client application using C/C++, or Fortran, use MATLAB Engine API for C, C++, and Fortran instead of an Automation server.

Call MATLAB Function from Visual Basic .NET Client
This example calls a user-defined MATLAB function named solve_bvp from
a Microsoft Visual Basic client application through a COM interface.
Call MATLAB Function from C# Client
This example shows how to call a user-defined MATLAB function, myfunc,
from a C# application.
Pass Complex Data to MATLAB from C# Client
This example creates complex data in the client C# program and passes it to MATLAB.
View MATLAB Functions from Visual Basic .NET Object Browser
You can find out what methods are available from a MATLAB Automation server using the Object Browser of your Microsoft Visual Basic client application.
Launch MATLAB as Automation Server in Desktop Mode
To launch MATLAB as a COM Automation server in full desktop
mode, use the programmatic identifier Matlab.Desktop.Application.
Manually Create Automation Server
Microsoft Windows operating system automatically creates an Automation server when a controller application first establishes a server connection.
Register MATLAB as Automation Server
To use MATLAB as an Automation server, you first must register the application in the Windows registry, which happens when you install a new version of MATLAB.
MATLAB COM Automation Server Interface
How to configure MATLAB software as a COM Automation server
To create a server, you need a programmatic identifier (ProgID) to identify the server.
Connect to Existing MATLAB Server
It is not always necessary to create a new instance of a MATLAB server whenever your application needs some task done in MATLAB.
Conversion of MATLAB Types to COM Types
How MATLAB converts data from MATLAB types to COM types.
Conversion of COM Types to MATLAB Types
How MATLAB converts data from a COM application into MATLAB types.
You can start the MATLAB Automation server in one of two modes – shared or dedicated.
To pass a VT_DATE type input to a Visual Basic program
or an ActiveX® control method, use the MATLAB class COM.date.
Data Types For Visual Basic .NET Clients
Data types for arguments and return values of server functions are expressed as Automation data types — language-independent types defined by the Automation protocol.
Use the Visible property to make MATLAB visible
in a server application.
MATLAB Application as DCOM Server
Distributed Component Object Model (DCOM) is a protocol that allows COM connections to be established over a network.
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.
