A = {[1 2 3],[4 5],6 ; [11 12],13,[] ; 21, [22 23], [24 25]} % data
B = arrayfun(@(k) cat(2,A{k,:}),1:size(A,1),'un',0) % make row vectors
C = padcat(B{:}) % pad vectors with NaNs
My function PADCAT can be downloaded here: https://uk.mathworks.com/matlabcentral/fileexchange/22909-padcat-varargin

yes that can be done using the above code. But what about when I am storing values from loops?

This is all rather vague ... Can you show us some code, showing where you get stuck?
