Are the file names such that there is 1 per line in the text file? If so, the following works for me. I've just changed your
t = [t,s]
to
t = [t;s]
fid = fopen('dbname.txt','r');
t=[];
tline = fgets(fid);
while ischar(tline)
disp(tline)
s=tline;
t= [t;s];
tline = fgets(fid);
end
fclose(fid);
celldata=cellstr(t);
Now you can access the individual file names with regular cell array indexing
celldata{1}
celldata{2}
