            'TasksToExecute',inf,...          
            'StartDelay',0,...

See

"I tried the try catch method but it doesn't help." &nbsp How did you use try-catch-end? I find the following "wrapper" useful

    function  called_by_timer(.) 
        try 
            the_real_function(.)
        catch me
            disp( getReport( me, 'extended', 'hyperlinks', 'on' ) )
        end
    end
