help with writing code for data post processing

Hi,

I have many data txt files that gives values of interest at different time steps (in order from start to finish). I am going to vary one parameter to change the initial conditions for each of the different run. My problem is that I want to take the same data in each file (at the same time step) compute the average of a given parameter at a given time step for each of the N files I generate (once I am able to do this I am going to plot the average(s) to reduce the overall noise in the data that I've been getting from just a single run). Therefore, I essentially want to make a final text file called averages.txt that I can use to plot the averages.

this is what I have so far.

PathStr = 'C:\data\';
textFiles = dir([PathStr '*.txt'])
fileID = fopen('averages.txt', 'w')
%r = # of rows per file, c = # columns per file
r =  % depends on files type
c = % depends on files type
MyData = zeros(r, c, length(textFiles)); 
Average = zeros(r, c);
for k = 1:length(textFiles)
  textFilename = ['data' num2str(k) '.txt'];
  fid = fopen(textFilename, 'rt');  %Open text file, 'rt' = read text file
  Data = textscan(fid,'%d %d %d %d %d %d\n', 'Delimiter',' ', c);    %Read file into c seperate variables
  for a = 1:r
  	for b = 1:c
  		Average(a,b) = Average(a,b) + MyData(a,b,:);
  		end
 	end	
	Average(:,:) = Average(:,:)/length(textFiles);
  fclose(fid);
end
save('averages.txt', 'Average(r,c)', '-ascii', '-double', '-tabs')
