Is there a way to run a function every time Matlab returns to its command prompt
显示 更早的评论
I would like to install a function that would run every time any other function has completed.
This might be a bit like "startup.m" but would run every time the command prompt is shown instead of at startup. I know Matlab runs "rehash.m" in this manner so maybe there is a way to add more fcns to run at this time.
Is there a way to do this?
Thanks
Ronan

A cheap method is to call all functions through a wrapper:
function varargout = wrapper(varargin)
varargout = cell(1, nargout)
[varargout{:}] = feval(varargin);
% Let the logging come here:
fprintf('returned at %s\n', datestr(now, 0));
Then you cannot just catch the return of the function, but the entry also.
Did you inspect the PROFILEr in detail? There are some undocumented features (look on Yair's pages).

If you can get the handle to the command window (I'm sure Yair has done similar things at some point; take a look around www.undocumentedmatlab.com), then you can probably change the FocusGained callback to execute your code. But I don't know if this would overwrite the existing callback for the command window. (I also don't know if there is an existing callback, or what it does).

If you have an open GUI, the focus does not return to the command window, although all functions are ready.
