MATLAB: I want to initialize class variables through array type class object using a function

classinitializing class variables

%%% Code for my class Nodes.m%%%%%%%%%%
classdef Nodes
      % Detailed explanation goes here
      % The node class contains the properties of each node
    properties (SetAccess = public)
        NodeID
        x
        y
        p=dlnode
        noNodes = 100
        uid = (1:100)
        InitialEnergy 
        ResidualEnergy 
        mark=0
        NodeStatus;
        Distance
        Dst
    end
end
%%%%%%%creating array type class object%%%%%
n(1, noOfNodes)= Nodes;
%%%%%%Function to initialize class variables%%%%
function Initialize( n,i,noOf Nodes)
for i=1:noOfNodes
  n(i).NodeID=i;
  x=rand();                %j;
  y=rand();                %k;
  n(i).x= x;
  n(i).y= y;
  n(i).InitialEnergy=2400.0;
  n(i).NodeStatus=0;
  n(i).mark=0;
  n(i).ResidualEnergy=n(i).InitialEnergy;
   n(i).NodeID= num2str(i); 
end
end 
%%%%%%%script file Test.m to call initialize funtion%%%%%%
clc;
clear;
% Initialization of Global Variables
Initialize( n,i,noOfNodes);
n = Nodes;
noOfNodes = 35;  %No. of Nodes
n.noNodes = noOfNodes;
NG = 3; %No. of Geocst Regions
GX = 500; % Maximum Value of x-coordinate
GY = 500; %Maxium Value of y-coordinate
LX = 0; % Minimum Value of x-coordinate
LY = 0; % Minimum Value of y-coordinate
The problem here is that though the variables get initializes using the function but they are not being stored in the work space. If I display them in the function I get the value but if work space the variables are not getting any values.

Best Answer

becuase Initialize is not returning any output argument to the workspace. You need this instead
 n = Initialize( n,i,noOfNodes);
and
function  n = Initialize( n,i,noOf Nodes)
    .....
end
Incidentally, it is curious that you do not define a class constructor, choosing instead to use the external function Initialize().
