Creating the MATLAB Server

Getting Started

To create a server, you need a programmatic identifier (ProgID) to identify the server. The ProgID for MATLAB® is matlab.application. For other MATLAB ProgIDs, see Programmatic Identifiers.

How you create an Automation server depends on the controller you are using. Consult your controller's documentation for this information.

If your controller is a MATLAB application and your server is another MATLAB application, you create the Automation server using the actxserver function:

h = actxserver('matlab.application')
h =

This command automatically creates the Automation server. You can also create the server manually. See Manually Create Automation Server.

Accessing Your Server from the Startup Folder

The MATLAB Automation server starts up in the matlabroot\bin\win32 folder. If this is not the MATLAB startup folder, the newly created server does not run the MATLAB startup file (startup.m) and does not have access to files in that folder.

To access files in the startup folder, do one of the following:

  • Set the server's working folder to the startup folder (using the cd function) and add the startup folder to the server's MATLAB path (using the addpath function).

  • Include the path name to the startup folder when referencing those files.

Get the Status of a MATLAB Automation Server

Use the enableservice function to determine the current state of a MATLAB Automation server. The function returns a logical value, where logical 1 (true) means MATLAB is an Automation server and logical 0 (false) means MATLAB is not an Automation server.

For example, if you type:


and MATLAB displays:

ans =

then MATLAB is currently an Automation server.

Creating a MATLAB Automation Server from Visual Basic .NET Application

If you use a Visual Basic® client application to access a MATLAB Automation server, you have two options for creating the server:

Accessing Methods from the Visual Basic Object Browser

You can use the Object Browser of your Visual Basic client application to see what methods are available from a MATLAB Automation server. To do this you need to reference the MATLAB type library in your Visual Basic project.

To set up your Visual Basic project:

  1. Select the Project menu.

  2. Select Reference from the subsequent menu.

  3. Check the box next to the MATLAB Application Type Library.

  4. Click OK.

In your Visual Basic code, use the New method to create the server:

Matlab = New MLApp.MLApp

View MATLAB Automation methods from the Visual Basic Object Browser under the Library called MLAPP.

Using CreateObject

To use the Visual Basic CreateObject method, type:

MatLab = CreateObject("Matlab.Application")
