Hi all,
I have a 1x100 cell (comprised of 2x500 doubles) and am trying to index through it 4 cells at a time. What I mean is that I would like to index cells 1-4, 9-12, then 17-20 and so on. Im having a bit of a hard time with this and would appreciate and comments or suggestions. Thank you!
An example:
for j = 1:4:100 % Index through 1x100 cell
for k = 1:4
temp{k}(1,:) = values{k}(1,:);
end
end
I will be editing this as I work on it! Thanks again!
EDIT: I found an answer to a similar question that proposed this:
idx = setdiff(2:10000,5:4:10000);
for ii = idx
disp(ii)
end
Again, the issue I run to here is that I can specify to skip every nth element but not a group of elements (i.e. 4 elements at a time).

E.g., is this the type of indexing you want?
for j = 1:4:100 % Index through 1x100 cell
temp = values(j:j+3); % Pick off the 4 cells
for k = 1:4
% Use temp{k} here
end
end

Thank you! This was very helpful and works. Another solution I came across was this (thanks to the cyclist):
idx = bsxfun(@plus,[0 1 2 3]',1:8:100)
for ii = idx(:)
% Do stuff
end
