Keep4

12 Mar 2005 (Updated 28 Aug 2006)

Keeps the listed variables in the calling workspace with a command format similar to "clear"

File Information
Description	This is another version of Keep, which allows a user to specify what variables are kept in the workspace of the calling routine. "Keep" compliments "Clear". This version has been extended to match the command format of the "clear" command for clearing variables. Thus wildcards and regular expressions are allowed. The version also supports the "global" key word and Keep will not touch global variables unless the "global" key word is used. Examples of supported formats: keep var1 var2 keep var* keep -regexp expr1 keep global keep global var1 keep global -regexp expr1
Acknowledgements	The author wishes to acknowledge the following in the creation of this submission: keep, keep2, KEEP3
MATLAB release	MATLAB 7.2 (R2006a)
Other requirements	None

01 Apr 2006	Bo Gao	very nice job!!
08 Jun 2006	David the Dude	Useful function but there is a bug: The function returns an error if only one workspace variable exists. To reproduce. Clear workspace initialize 1 variable X and run keep(X)
29 Aug 2006	Mirko Hrovat	Thanks to David for pointing out the bug when there are no variables to delete. This generated an unnecessary error message. Comments were also improved to delineate the examples more clearly.

28 Jun 2006	Another bug fix which fixes the same issue as the prior bug fix but with global variables.
