hi, i am developing a code where i have 2 functions: the first function gives me a smaller matrix 'k'.
i want to obtain this 'k' matrix for every iteration.
then i want to add these smaller matrices into a larger one, for that i am using the second for loop.
can anyone please guide me on how i can save each 'k' matrix after every iteration, and then use the 'k' matrices and add them to a larger matrix 'K'?

Ran in:
posr = 4;
posc = 3;
m = rand(6);
M = zeros(120);
M(posr:posr+5,posc:posc+5) = m
M = 120x120

Here are two possibilities:
% Save into cell arrays
nsmall = 4;
mcell = cell(nsmall,1);
for k = 1:nsmall
mcell{k} = rand(3); % Note curly brackets, to save as *contents* of the cell
end
% Save each matrix as a "slice" of a three-dimensional array
nsmall = 4;
m3d = zeros(3,3,nsmall);
for k = 1:nsmall
m3d(:,:,k) = rand(3); % Saving each slike
end
