Test #5 seems false:
I guess "a = sprintf('\ttab in front, space at end ');" should be a = '\ttab in front, space at end '.
Besides, tab is ASCII 9 (not 32).

@Franck..use isspace function. There is a difference between whitespace and tab space! BTW strtrim removes both white and tab space !

This problem should probably contain a test with only spaces as well. That requires solutions to be much more robust.
