Set i = 1: end of file - matlab

Question

I am trying to have MATLAB read in a list of files. However, I have several lists of these files and they are all different lengths. How can I set a for loop so that the i goes from 1 to the end of the file? (The line I'm talking about is the 'for i = 1:END OF FILE' part.
To illustrate, the first few lines of my .dat file looks like this:
2006-01-003-0010.mat
2006-01-027-0001.mat
2006-01-033-1002.mat
2006-01-051-0001.mat
2006-01-055-0011.mat
My code looks like this:
for y = 1:9
flist = fopen([num2str(year(y))'_MDA8_mat.dat']); % Open the list of file names - CSV files of states with data under consideration
nt = 0; % Counter will go up one for each file loaded
while ~feof(flist) % While end of file has not been reached
for i = 1:END OF FILE % Number of files CHECK EACH TIME FILE IS MODIFIED
fname = fgetl(flist); % Reads next line of list, which is the name of the next data file
disp(fname); % Stores name as string in fname
nt = nt+1; % Time index
load (fname, 'site_data'); % Load current file. It is all the data for one site for one year
O3_data{i} = site_data;
% Stuff
end
end

Answer 1

Try this code :
for y = 1:9
flist = fopen([num2str(year(y))'_MDA8_mat.dat']); % Open the list of file names - CSV files of states with data under consideration
while ~feof(flist) % While end of file has not been reached
newFileName = fgetl(flist);
fid = fopen(newFileName);
while ~feof(fid)
currentLine = fgetl(fid);
% Do stuff on each sub-file
end
fclose(fid);
end
flcose(flist);
end
There another while check you can do like this :
flist = fopen([num2str(year(y))'_MDA8_mat.dat']);
line = fgetl(flist);
while(ischar(line))
%Do process (like open next file with the line variable)
%read the next line
line = fgetl(flist);
end
