I need to save 'E' for each value of k;
Thanks Any help is appreciated!

The easiest way to probably to just use a cell array.
Es = cell(100,1)
for i = 1:100 %your loop
% do stuff; generate E
Es{i} = E
end
I'm assuming you already have the loop working, you're just trying to save the output. This will be stored in Es.

It would probably be difficult; all your vectors are of different sizes, which means you can't just stack them into a big matrix. If you knew they had a max size M then you could do this:
Es = NaN(100,M);
for i = 1:100 %your loop
%do stuff, generate E
Es(1:length(E)) = E;
end
This will store E in the first elements of Es for each row; the rest will be NaN values. The problem is that this is pretty inefficient in terms of memory, but it might work. You also need to know M which is difficult.
