Hello everyone!

I would be much appreciated if you can help dealing with an easy problem

I have a cell called voltage with dimensions 10x48x28. Each one of the 10 contains a double with size 10x10000. I would like to calculate the mean in order to have 28x48 cell.

Thank you in advance for your kind help and support! Alexandra

Do you want the size of each cell in the mean array (28x48) to be 10x10000? Or something else?

在 MATLAB Online 中打开

[n,m,p]=size(voltage);
v=cell2mat(voltage);
w=permute(v,[2 1 3]);
[ii,jj,kk]=size(v);
for k=1:p
  f(:,:,k)=mean(reshape(w(:,:,k),jj,10,[]),3)';
end
out=mat2cell(f,2,ones(1,jj),ones(1,kk));
d=permute(out,([2 3 1]));
