mtx2charcell

%charcell = mtx2charcell(mtx)
% Converts a matrix of numbers into a cell array of strings of the same
% dimensionality as MTX.
%charcell = mtx2charcell(mtx,fmt)
% Uses the format string FMT (see SPRINTF for details).
%
%This function serves as a shorthand for using the built-in NUM2CELL,
%NUM2STR, and RESHAPE commands together (thanks Urs Schwarz!)
%
%EXAMPLES:
% mtx2charcell([0 1 2]) --> {'0.000000', '1.000000', '2.000000'}
% mtx2charcell([0 1 2], '%d') --> {'0', '1', '2'}
%
%This function can be handy to use in conjunction with the author's JOIN
%function (also available on Matlab Central). For example,
% join('-', mtx2charcell([0 1 2], '%d')) --> '0-1-2'
