logical2cellstr(tf)

function c = logical2cellstr(tf)
% Converts logical arrays to cell array of strings.
% 
% C = LOGICAL2CELLSTR(TF) takes a logical array TF, and returns a cell
% array of strings, with the value 'true' wherever  TF is true, and
% 'false' wherever TF is false.
% 
% EXAMPLE:
% logical2cellstr([true false; false true])
% ans = 
%     'true'     'false'
%     'false'    'true'
