Introducing MATLAB ActiveX Integration
7-5
In general, servers that are not controls will not be physically or visually
embedded in the client application. (MATLAB is a good example — MATLAB
is not itself a control, but it is a server. So, MATLAB cannot be physically
embedded within another client. However, since MATLAB is a control
container, other ActiveX controls can be embedded within MATLAB.)
In addition, MATLAB ships with a very simple sample ActiveX control that
draws a circle on the screen and displays some text. This allows MATLAB users
to try out MATLAB’s ActiveX control support with a known control. For more
information, see “MATLAB Sample Control” on page 7-13.
