1) Create your own fprintf function in a folder on the path (e.g. local folder) with code similar to:
function nbytes = fprintf(varargin)
nbytes = builtin('fprintf', varargin{:}); %call built-in fprintf
keyboard; %or pause. keyboard is probably more useful
end
2) run your code and do whatever it is you want to do when it breaks into the debugger in your custom fprintf function
3) when done, don't forget to get rid of the custom fprintf
4)in future, make sure that your debugging message include the name of the script/function that emits the message. Better than fprintf use warning which automatically displays that information.
