Hi all,
I got a cell whose form is as follow :
data{number_of_file,1}(number_of_line,number_of_columns)
I'd like to average over, for instance, the first line of the first column over all files, then the second line of the first column over all files, etc.
What would you suggest ? I've tried :
for j=1:length(data{1,1}) % loop over all lines
meanP=nanmean(data{:,1}(j,1)); % loop over all files for the j line
end
But I end up with this message : Bad cell reference operation.
Thanks
Florian

You want the average of per-line of all the files? If all of the data are the same number of rows, then you can concatenate them together and average the rows in one line:
data{1,1}=rand(3,3);
data{2,1}=rand(3,3);
meanP=nanmean(horzcat(data{:,1}),2); %by row
Or by column:
meanP=nanmean(vertcat(data{:,1}),1); %by column
