Hi,

I have a question about inner Matlab error management. Right now I have quite a large program with a lot of variables and functions that cumulated over my code writting and I'm 100 percent sure that I did not catch all the bugs and mistakes in the program and I don't want it to crash completely when is used by layman user. So, is there a way to display errordlg message and for example restart the program when there will be any given error directly by Matlab (for example when I forgot to declare a global variable etc.)?

Thanks for answers, Peter

For those that will have the same problem...solution might look something like this if you use GUI...

function varargout = Program(varargin)
try
      gui_Singleton = 1;
      gui_State = struct('gui_Name',       mfilename, ...
                         'gui_Singleton',  gui_Singleton, ...
                         'gui_OpeningFcn', @program_OpeningFcn, ...
                         'gui_OutputFcn',  @program_OutputFcn, ...
                         'gui_LayoutFcn',  [] , ...
                         'gui_Callback',   []);
      if nargin && ischar(varargin{1})
          gui_State.gui_Callback = str2func(varargin{1});
      end
      if nargout
          [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
      else
          gui_mainfcn(gui_State, varargin{:});
      end
catch exception
      beep
      h = errordlg('Unexpected error, the program will be restarted.','Syntax      
      error','modal');
      uiwait(h)
      Program
end
