Hi all,

I have a 7x1 cell for which I would like to apply a butterworth filter to all cell arrays. Any idea how to do it?

filtfilt(b,a,mycell{:,1:7});
Index in position 2 exceeds array bounds (must not exceed 1).

Thanks

You cell has the size {7x1}, not {1x7}.

filter needs one numerical vector or matrix as input. So use a loop:

result = cell(1, 7);
for k = 1:7
  result{k} = filter(b, a, T_or_x_cycle{k});
end
