Hi Im reading excel files and storing them into data{k} so my data is 1x34 cell and each cell is a double, with variable column number and fixed row 13, now i want to calculate mean of 34 files for column and row 1 and do the same for the rest.I tried cell2mat but this doesnt work as i have different values for columns.
folder='E:\Engine image\E100 cycles\All Excel Files';
filetype='*.xlsx';
f=fullfile(folder,filetype);
d=dir(f);
for k=1:numel(d);
data{k}=xlsread(fullfile(folder,d(k).name));
end

EDIT
m = numel(data);
[ii,~]= cellfun(@size,data);
a = nan(max(ii),size(data{1},2),m);
for jj = 1:m
a(1:ii(jj),:,jj) = data{jj};
end
out = nanmean(a,3);

This is not clear, to make your problem clear, you can post a short example, and also post the expected result, you haven't specified clearly what mean we have to calculate. You said also, that your matrices are not the same sizes
