File Information
Description	This is another modified version of the original KEEP M-file by Xiaoning (David) Yang (1998). It allows the user to specify some variables and clear the rest, and uses the same syntax as the clear command. The main contribution of this code is that it allows the use of the wildcard * in exactly the same fashion as the clear command. keep3 var1 var2 Clears all variables expect var1 and var2 keep3 va*2 Clears all variables expect those whose names begin with 'va' and end with '2'. Requires Matlab 6.5 (R13) because it makes use of the regexp command.

12 Jan 2004	Fixed a bug that caused KEEP3 to clear all variables when there where no variables to clear. It now works just fine.
