07 Feb 2012	David	Very useful. However, there is an error when the input vector contains both a value that needs a prefix, and one that does not. (i.e. [10 0.001]). Modification to output cell arrays instead of string arrays will fix the error. Alternatively, changing strvcat to char will also fix the error, but you'll be left with an extra space on those values without a prefix.

12 Aug 2008	Incorrect use of cat, instead of strvcat was causing error for some input vectors...oops!
