From: Markus Due Jakobsen on 28 Jul 2010 08:16 Hi Is there someway to gather a cellarray by each row without using a loop (example 1) and without leaving whitespaces between each gathered column? % ============================= A={'One','two';'three','four'}; % Example 1: Loop [Row Col] = size(A); G = cell(Row,1); for j=1:Row G(j) = {[char(A(j,Col-1)) char(A(j,Col))]}; end % With the loop G looks like this, no space between "one" and "two"... % G = % 'Onetwo' % 'threefour' % Example 2: Vectorized % Another method could be this way, but this method leaves a space between % "one" and "two"... Obs: deblank or strtrim doesn't remove the space G1 = cellstr([char(A{:,1}) char(A{:,2})]); % G1 = % 'One two' % 'threefour' % ============================= Kind regards Markus
