Hi, Could you please help me?

I have created a GUI in Matlab and I want to excute a certain function every x seconds. I have used a timer function, but I am getting the following error:

??? Error while evaluating TimerFcn for timer 'timer-11' 
CAT arguments dimensions are not consistent.

I don't know because I am getting the CAT arguments error.

The code is something like this.

I create the timer function just before the GUI is made visible:

handles.tmr = timer('TimerFcn',{@TmrFcn,handles.guifig},'BusyMode','Queue',...
    'ExecutionMode','FixedRate','Period',0.5);

Then in the core code of the GUI, I excute the timer function once:

     if (i>610)&&(x==0)
          start(handles.tmr);
          x=1;
     end;

The timer function is as follow:

function TmrFcn(src,event,handles) %Timer function
global v2 %where v2 is a vector of constant size that keeps changing its content.
handles = guidata(handles);
[loc]=PruebaVF(v2); % Here I call a function to be executed.
end

Thanks
