The only way I see to do it is to clear each variable individually ..... clear (x,y,z,....) That can be a lot of typing in a large sheet and you might miss one. I've had a few situations where I'd like to just clear everything and have a section of my worksheet act individually without any worry of using prior values but without having to relabel everything. The documentation doesn't point to any solution, but I know there are occasionally undocumented techniques.
Thanks,
