path2cell

PATH2CELL Convert search path to cell array.

   PATH2CELL returns a cell array where each element is a directory
   in the search path.

   PATH2CELL(MYPATH) converts MYPATH rather than the search path.

   Empty directories are removed, so under UNIX, PATH2CELL('foo::bar')
   returns {'foo', 'bar'} rather than {'foo', '', 'bar'}.
