averages of cell array

I have the following script for importing text files into matlab which include hourly data, where I am then trying to convert them into daily averages:

clear all 
pathName = ...
TopFolder = pathName; 
dirListing = dir(fullfile(TopFolder,'*.txt'));%Lists the folders in the directory specified by pathName.

for i = 1:length(dirListing);
    SubFolder{i} = dirListing(i,1).name;%obtain the name of each folder in
            %the specified path.
end

%import data
  for i=1:length(SubFolder);
      rawData1{i} = importdata(fullfile(pathName,SubFolder{i}));
  end

%convert into daily averages
  rawData2=cell2mat(rawData1);
      %create one matrix for entire data set
  altered=reshape(rawData2,24,(size(rawData2,2)*365));
      %convert into daily values
  altered=mean(altered)';
      %take the average for each day
  altered=reshape(altered,365,size(rawData2,2));
      %convert back into original format

My problem lies in trying to convert the data back into the same format as 'rawData1' which was a cell for each variable (where each variable is denoted by 'SubFolder'. The reason for doing this is that all but one of the variables are vectors, where the remaining variable is a matrix (8760*11).

So, an example of this would be:

clear all 

cell_1 = rand(8760,1); 
cell_2 = rand(8760,1);
cell_3 = rand(8760,1);
cell_4 = rand(8760,1);
cell_5 = rand(8760,1);
cell_6 = rand(8760,11);
cell_7 = rand(8760,1);
cell_8 = rand(8760,1);
cell_9 = rand(8760,1);

data = {cell_1,cell_2,cell_3,cell_4,cell_5,cell_6,cell_7,cell_8,cell_9};

Where I need to convert each cell in 'data' from hourly values into daily averages (i.e. 365 rows).

Any advice would be much appreciated.

try this is

pathName = ...
TopFolder = pathName; 
dirListing = dir(fullfile(TopFolder,'*.txt'));
cell_all = arrayfun(@(i1)importdata(fullfile(pathName,dirListing(i1,1).name)),(1:length(dirListing))','un',0);
d = cat(2,cell_all{:});
d2 = squeeze(mean(reshape(d,24,size(d,1)/24,[])));
out = mat2cell(d2,size(d2,1),cellfun('size',cell_all,2)).';
