Initialization Command
The Initialization command parameter is a string that sets the initial
conditions of the ActiveX Control block. The string is evaluated during the
model initialization stage.
The handle of the ActiveX Control block is
hActX.
Other Events and Handlers
The Other events and handlers parameter specifies actions taken by the
ActiveX Control block when you perform a defined action on the ActiveX
Control block. You must enter an event as an
nx2 cell array. The first entry in
each row must be the name of the ActiveX event. The second entry in each row
must be the MATLAB callback to be executed.
For a list and description of supported events for an ActiveX control, consult
the ActiveX control’s help.
