How can I make each cell array consistent in length?

Question

0 个投票

I'm really grateful for anyone telling me how to make cell arrays equal in length (please find attached). The following code doesn'y work.

N = cellfun(@numel, T_mon);

>> M = min(N);

>> newN = M * ceil(N / M);

>> padfun = @(k) [T_mon{k} zeros(1, newN(k) - N(k))] ;

>> T_mon_new = arrayfun(padfun, 1:numel(T_mon) , 'un', 0) ;

Error using horzcat

Dimensions of matrices being concatenated are not consistent.

Error in @(k)[T_mon{k},zeros(1,newN(k)-N(k))]

Do you mean this?

N = cellfun(@numel, T_mon);
M = max(N);
T_mon_new = cellfun(@(a) [a; zeros(M - numel(a),1)],T_mon,'uni',0);

Yes, just changing:

N = cellfun(@numel, T_mon);
M = max(N);
T_mon_new = cellfun(@(a) [a; nan(M - numel(a),1)],T_mon,'uni',0);

Thanks, I really appreciate
