function c = cellstr(s)

%CELLSTR Create cell array of character vectors

%   C = CELLSTR(S) converts S to a cell array of character vectors.

%   If S is a string array, then CELLSTR converts each element of S.

%   If S is a character array, then CELLSTR places each row into a

%   separate cell of C. Any trailing spaces in the character vectors are 

%   removed.

%

%   Use STRING to convert C to a string array, or CHAR to convert C

%   to a character array.

%

%   Another way to create a cell array of character vectors is by using 

%   curly braces:

%      C = {'hello' 'yes' 'no' 'goodbye'};

%
