I've posted an updated version which works with MATLAB R2014a:


nice tool, I'm new with regexp an using this it's much easier to test some cases :-)

Im no expert at regexp. But this makes it easy to do my regexping. It highlights your matches as you type, this instant feedback is something I have been looking for.

I've updated the GUI to include tool tips, as well as including the help section in the M-file. This version should be easier to use.

Please post some help for this file - I know what regexp are, but I haven't got a clue how the author expects this to be used - what goes where, what fields can be modified and how, etc.
