Error while evaluating TimerFcn for timer 'timer-1' yes, the snippet was meant to be used in the command window (copy/paste or a simple script) to show a crude sequence of commands, which do what you want - including the fact that the command string COM uses the var SH (instead of UD(1)), which only is valid in this context... now, if you want to place the idea into a function, this might be a solution function tmsg(varargin) % - add options by employing the VARARGIN args in your function, eg, % - period, message box title, and so on... % the messagebox mh=msgbox('foo','timing...'); % - handle to its text obj sh=findobj(mh,'tag','MessageBox'); % the timer th=timer(... 'executionmode','fixedrate',... 'period',1,... 'timerfcn',{@tcb,sh,clock}); start(th); uiwait(mh,10); stop(th); delete(th); if ishandle(mh) close(mh); end end % timer callback function function tcb(this,dummy,mhdl,clk) %#ok set(mhdl,'string',round(etime(clock,clk))); end us
