I have a cell array M with 4 cell elements and each cell element has a 8x2 matrix.
I'm trying to making different combinations using nested for loops as
n = length(M);
[s,d] = cellfun(@size,M);
ncombs = prod(s);
P = cell(1,ncombs);
k = 0;
for i = 1:size(M{1},1)
for j = 1:size(M{2},1)
for x = 1:size(M{3},1)
for y = 1:size(M{4},1)
k = k+1;
P{k} = [M{1}(i,:);M{2}(j,:);M{3}(x,:);M{4}(y,:)];
end
end
end
end
Now in this case, I have n = 4 and hence 4 nested loops. Can I generalize this thing with any n? For example like for n = 2, 2 nested loops and correspondingly P{k} becomes [M{1}(i,:),M{2}(j,:)]

It doesn't make much sense for them to be a cell array in that case. You could have an 8x2x4 matrix.
