I have a 490X1 cell array (let's call it Output) in which each cell is a 300X300 double. I also have a vector C with dimensions 1X160 which contains row numbers. I want to create another 490X1 cell array where each cell will be a 160X160 double and the selected 160 rows and columns are taken from the row numbers provided in vector C. I know that it can be done through a loop with some logical conditions, but I don't know how to design the codes. Can someone help me out?

D = Output; % preallocate
for k = 1:numel(D)
D{k} = Output{k}(C,:);
end
