Cell arrays of strings in "sort" and "unique"

[Keith Goodman]

I noticed that the functions "sort and "unique" do not support cell
arrays of strings. And that sort does not support strings.

As a work around for unique, I'm using

function [z,i] = unique_cell(x)
x = x(:);
y = str2num(num2str(-1*char(x)));
[ignore,i] = unique(y);
z = x(i,:);

Could the above technique of converting a cell array to a char array
to a number matrix to a string array to a number array be used in sort
and unique to handle cell arrays of strings?
