15. Amachine cuts N pieces of a pipe. After each cut, each of pipe is weighed piece and its length is measured; these two values are then stored in a file called pipedat (first the weight and then the length on each line of the file). Ignoring units, the weight is supposed to be between 2.1 and 2.3, inclusive, and the length is supposed to be between 103 and 104, inclusive. The following is just the begin ning of what will be a long script to work with these data. For now, the script will just count how many rejects there are A reject is any piece of pipe that has an

Explanation / Answer

fid = fopen('pipe.dat');
r = 0;
while ~feof(fid)
t1 = fgets(fid);
c = textscan(t1,'%f %f');
w = c{1};
l = c{2};
%disp(w);
%disp(l);
  
if (w < 2.1 || w > 2.3)
r = r + 1;
end
if (l < 10.3 || l > 10.4)
r = r + 1;
end
end

fprintf(' There were %d rejects. ', r);
