Hey all!
I have 254 files named blah_blah_001 until blah_blah_254. Each file has 723 x 3127 dimension and I want to combine all to create a 723 x 3127 x 254 matrix. I have tried loops but I am not sure how to write so that each file number is with 3 digits. Here is my attempt:
all = NaN(723,3127,254);
% attempt to put all arcs together..
for i=1:254;
for arc = 001:254;
all(:,:,i) = [TJJ_arc_(arc)]
end;
end;
After this I wish to calculate a nanmean to get 723 x 254...
Can someone help me?

allData = NaN(723,3127,254);
for k=1:254
% create the file name
filename = sprintf('TJJ_arc_%03d.mat',k);
% load the data
data = load(filename);
% save the data
allData(:,:,k) = data;
end
NOTE that all is a built-in MATLAB function so your code should avoid using this as a variable name.
NOTE also how I replaced your iterator i with k. i and j are used in MATLAB as the representation of the imaginary number, so it is good practice to avoid using them in for loops.
Try the above and see what happens!

Cool. You may want to change the above filename variable to varname so that it is clear that a variable named whatever is being loaded rather than a file.
