Test for end-of-file
status = feof(fileID)
status = feof(fileID)1 if
a previous operation set the end-of-file indicator for the specified
file. Otherwise, feof returns 0. fileID is
an integer file identifier obtained from fopen.
Opening an empty file does not set the
end-of-file indicator. Read operations, and the fseek and frewind functions,
move the file position indicator.
Read bench.dat, which contains MATLAB® benchmark
data, one character at a time:
fid = fopen('bench.dat');
k = 0;
while ~feof(fid)
curr = fscanf(fid,'%c',1);
if ~isempty(curr)
k = k+1;
benchstr(k) = curr;
end
end
fclose(fid);
