[Martin Lenz]

many users don't have a version like r2008a or newer. this function is also necessary. thank's a lot.

[Federico Ang]

not everyone uses r2008a if you people would only realize that...

[William Vidal]

You've saved my project...

[fex observer]

If these two well-known reviewers tell the truth, you should remove this submission.

[Urs (us) Schwarz]

yet another one of these KEEP-ers...
note: r2008a (finally) introduces CLEARVARS with these options

clearvars -except v1 v2 ...
clearvars -except -regexp p1 p2 ...
clearvars v1 v2 ... -except -regexp p1 p2 ...
clearvars -regexp p1 p2 ... -except v1 v2 ...

This functionality has been posted to the FEX many times, e.g., keep, keep2, keep3. This functionality also exists as part of MATLAB itself starting with R2008a, i.e.,

clearvars -except v1 v2 ... clears all variables except for those specified following the -except flag. Use the wildcard character '*' in a variable name to exclude variables that match a pattern from being cleared. clearvars -except X* clears all the variables in the current workspace, except for those that start with X, for instance.
