Hi All

I'm trying to create my first class and I'm struggeling to define my property as a fixed 'simulink.bus' type. I created a simulink.bus (struct) 'ST_DATARECORD' with (at this moment) 2 variables. I want to use this bus to define the internal property.

classdef myFunct < matlab.System
    properties (Access = public)
		bCmdAddDataPrevScan uint8 = 0
		arrstDataBuffer ST_DATARECORD			            % Buffer holding the supplied data
		nWriteIndex uint16 = 0
	end
    function obj = mAddData(obj,i_Input)
		obj.arrstDataBuffer.variable1 = i_Input;			% Copy input data to buffer location
	end
end

How to create this? The simulink.bus definition is available in my workspace. The supplied code above is only an example (pseudo) code, so I can understand what to do. Thanks for any anser.

Regards

Ludo

I found an example for a declaration here, but this only displays the default 'double'. How to change this to a 'simulink.bus' type??

classdef ValidationExample

properties

MyPublicData (1,:) double {mustBePositive} = [1 1 1]

end

在 MATLAB Online 中打开

Finally got it to work :-)

The array has now a fixed size of 2 records of the datatype ST_DATARECORD

classdef myFunct < matlab.System
    properties (Access = public)
		bCmdAddDataPrevScan uint8 = 0
		arrstDataBuffer(:,2) = Simulink.Bus.createMATLABStruct('ST_DATARECORD')     % Buffer holding the supplied data
		nWriteIndex uint16 = 0
	end
    function obj = mAddData(obj,i_Input)
		obj.arrstDataBuffer.variable1 = i_Input;			% Copy input data to buffer location
	end
end
