clear all; clc;clf; 
for k=1:5; 
cos_el=R*cos(Elev);
asin_x=asin(cos_el);
cos_y=cos(asin_x);
vtec=stec.*(cos_y); 
gistm =[ut, vtec]; 
TV_A{k}=ut; 
L(k)=length(ut); 
end

Following my coding. So i have 5 ut data and 5 vtec data. I need to find highest length of ut seems i have 5 ut data. then the highest length of ut data need to be in the first column in a new .mat form and following up by the other 5 vtec data. the 5 vtec data have to follow according the highest length of ut and seems the vtec data dimension are not same it must filled up with NaN or 0.

Let Ut - cell array 1 x 5 , contains column vectors with size n(k) x 1, for k = 1:5.

Vtec - cell array 1 x 5, contains vector m x 1, here all m <= max(n).

e.g. data:

Ut = arrayfun(@(ii)ii*ones(randi(10),1),1:5,'un',0);
Vtec = arrayfun(@(ii)ii*ones(randi(6),1),1:5,'un',0);
% solution
n = max(cellfun('length',Ut));
out = cellfun(@(x)[x;nan(n-numel(x),1)],Vtec,'un',0);
