Accessing multiple cells from char array

Dear all, I have a problem with the following: in a directory I store 12 *mat files - each of these files store one variable, 'averages'. Each 'averages' is a 1xn cell array of various lengths for different *mat files(i.e. 'averages' for 1.mat is of length 9, and 'averages' for 2.mat is of length 6 etc.). I need to load all of those files from directory and perform a cross-correlation between vectors of the same length that I store in each of the cells of all of 'averages' from different *mat files. I wanted to use this:

Folder   = 'C:...'
FileList = dir(fullfile(Folder, '*.mat'));
nFile    = numel(FileList);

for i1 = 1:nFile
  file1 = fullfile(Folder, FileList(i1).name);
  for i2 = i1+1:nFile
    file2 = fullfile(Folder, FileList(i2).name);
     ...
  end
end

- but the problem is, I have multiple cells within each of my *mat files and not sure how to operate within the character string arrays.

This is what I do witin one 'averages' file, and I would like to do the same between all of 'averages' *mat files:

corr_out = zeros(length(averages),length(averages));

for m=1:length(all_files);
    for p=1:length(averages);
        for r=p+1:length(averages);
            corr_out(p,r) = xcorr(averages{1,p}(:)',averages{1,r}(:)',0,'coeff');
        end
    end
end

I am attaching two exemplary 'averages' files. Would be very grateful for your help!

First just load all of the files, and put the required data into a cell array:

Folder   = 'C:...'
FileList = dir(fullfile(Folder, '*.mat'));
nFile    = numel(FileList);
cFile    = cell(1,nFile);
for k = 1:nFile
    F = fullfile(Folder, FileList(k).name);
    S = load(F);
    cFile{k} = S.averages;
end

and then do your cross correlation on the contents of the cell array cFile.

Thanks Stephen! Much appreciated.
