Hello,

I have a 1x11 cell array. Each element in the array is 128 x 1000 matrix (see figure). How can I extract the [9 10 11 12 13 28 29 30 31 32 33 34] from each element and compute the mean of these elements, so that the resultant element will be the mean[9 10 11 12 13 28 29 30 31 32 33 34] x1000 (i.e. 1x1000) in each of the 1x11 cell array. Thanks,

By far the easiest way is to use a loop.

SubB_M1power={rand(128,3),rand(128,3)};
for n=1:numel(SubB_M1power)
    SubB_M1power{n}=mean(SubB_M1power{n},1);
end
SubB_M1power
SubB_M1power = 1×2 cell array
    {[0.5482 0.4864 0.5036]}    {[0.4972 0.5038 0.5269]}
