Hi, I've wrote a baseStation class matlab class, which constructor is given as following:

function obj = baseStation(btscoord,btsid,attachedcell,aa,tx,sirmin,rxmax,rxmin,txmax,txmin) 
            nargin
           if  nargin <3   
               aa=0;
               tx=0;
               sirmin=0;
               rxmax=0;
               rxmin=0;txmax=0;txmin=0;
           end
            %call the superconstructor   
            obj = obj@btsRadio(aa,tx,sirmin,rxmax,rxmin,txmax,txmin);
            %initiate class variable
                  obj.btsID = btsid;
                  obj.btsCoord = btscoord;
                  obj.attachedCell = attachedcell;
                  obj.btsInfo = importdata('btsInfo.mat'); 
          end

when i try to call it in a nested for-loop, the second loop doesn't execute and an error occur : not enougth imput argument. The subclass baseStation seems not to receive arguments from last loop. I actually want to create an array object. Do someone tell me what I'm doing wrong?

thanks for your help

Bolivar

Will you be posting the exact error message? That would help solve your problem.

I suspect you are running into problems with subscripting the object. Try instead, to create the first object as, a(1) = baseStation(args{:}) a(2) = baseStation(args{:})

should work and build what you are looking for.

@Bolivar: What about using repmat()?

Bolivar 2013-7-1

repmat just make copies of the given object. That's mean the resulting array all have the same handle(a change in one object's Property brings change in all the other) which isn't actually what i'm expecting then all object in the array should be unique. nevertheless thanks
