06 Oct 2009 zoom2cursor Dynamic, scalable zoom following the motion of the cursor; also displays the current position. Author: Brett Shoelson

Very useful, thanks.
For those wondering how to exit the function, just click on 'X'.

I've found useful to create a 'exit_zoom2cursor' function.
If you're interested, comment the statement 'endbutton = ...'
And call this function:

function exit_zoom2cursor
zoomparams = getappdata(gcf,'zoomparams');
if isempty(zoomparams)
    return;
end;
set(gcf,'windowbuttonmotionfcn',zoomparams.oldwbmf);
set(zoomparams.currax,'units',zoomparams.oldaxunits,'xlim',zoomparams.oldxlim,'ylim',zoomparams.oldylim);
set(get(zoomparams.currax,'children'),'buttondownfcn',zoomparams.bdfcnold,'busyaction',zoomparams.baold);
set(gcf,'pointer',zoomparams.oldpointer,'doublebuffer',zoomparams.dbold);
