Specify function to run
Configure MessageReceivedFcn as a callback function to run a string expression, a function handle, or a cell array when a specified number of messages are available.
The MessageReceivedFcnCount property defines the number of messages available before the configured MessageReceivedFcn runs.
The default value is an empty string. You can specify the name of a callback function that you want to run when the specified number of messages are available.
canch.MessageReceivedFcn = @Myfunction
You can also use the set function to set the values of this property.
