Array formation and parentheses-style indexing with objects of class 'nodeClass' is not allowed. Use objects of class 'nodeClass' only as scalars or use a cell array.

I have extended the helperPacketizedModemNode class to nodeClass with 2 properties

classdef nodeClass < helperPacketizedModemNode

properties

Energy = 100

isClusterHead = true

end

methods

function obj = nodeClass(addr)

obj.Address = addr;

obj.DestinationList = 0;

obj.Energy = 100;

obj.isClusterHead = true;

obj.NumPayloadBits = 19530;

obj.PacketArrivalRate= 0.2;

obj.ACKTimeOut = 0.25;

obj.MaxBackoffTime = 10;

obj.MaxDataRetries = 5;

obj.QueueSize = 10;

obj.CarrierDetectorThreshold = 1e-5;

obj.AGCMaxPowerGain = 65;

obj.SamplesPerFrame = 2000;

obj.Verbose = true;

obj.SampleRate = 200e3;

end

end

end

for i = 1:5

node(i) = nodeClass(1);

end

Hi,

You can try replacing node(i) with node{i} to store object .

You can refer to below link for more information

Hope it helps

The helperPacketizedModemNode class used in, among other places, this example specifically disallows being stored as a non-scalar array of objects. You can create a scalar helperPacketizedModemNode object or you could create a cell array of helperPacketizedModemNode objects but you cannot create (as you're trying to do) a 5 element array of them.
