Say I have a 100x100 cell.

I want to get all the rows where the 9th column is equal to 3, and all the rows where this isn't the case. These would be stored in two separate variables.

How would I do this?

I think the code will be like this:

% 100x100 sample cell array
C = num2cell(randi(10,100,100));
% Rows where the 9th column is equal to 3
idx = cellfun(@(x) isequal(x,3), C(:,9));
% Extract the target rows
C1 = C(idx,:);
% Others
C2 = C(~idx,:);
