I am new to coding my own blocks, and quickly ran into something I do not understand. When I simply add an empty vector as a property to my block as in the code below, I get an error (Invalid setting in block 'Dataflow/MATLAB Discrete-Event System' for parameter 'InputRateVector') but only after I try to run a simulation. It seems that having an empty vector as a property is okay, but having an empty vector as block parameter is not. Why is that? (For my purpose, having an empty vector really makes sense in some situations...)
PS. The code below is simply the standard "MatlabBlock" definition for discrete event systems, with one line added to create the property and two functions added to make sure there are no inputs or outputs to this block (that will change later when I understand what happened here...).
Thnx. Pieter
classdef MyBlock < matlab.DiscreteEventSystem & matlab.system.mixin.Propagates
properties
InputRateVector = [ ];
end
properties (DiscreteState)
end
properties (Access = private)
end
methods (Access = protected)
function num = getNumInputsImpl(obj)
num = 0;
end
function num = getNumOutputsImpl(obj)
num = 0;
end
function setupImpl(obj,u)
end
function [entity, events] = entryImpl(obj, storage, entity, source)
events = [];
end
function resetImpl(obj)
end
end
end
