function tf = strlexcmp(a, b)
%STRLEXCMP Lexicographic comparison of two strings.
%   STRLEXCMP(A, B) returns -1, 0, or 1 depending on whether the left argument
%   is stringwise less than, equal to, or greater than the right argument.
%   This is a MATLAB version of the Perl `cmp' operator.
%   See also EQ, ISEQUAL.
