num = load('YourFile.txt') ;
for K = 1 : size(num, 1)
  First = num(K, 1);
  Second = num(K, 2);
  Third = num(K, 3);
  Last = num(K, 4);
  Do whatever at this point

MATLAB: Data with different length of rows

Try this:

fidi = fopen('file.txt','rt');
k = 1;
while ~feof(fidi)
    row = fgetl(fidi);
    avg(k,:) = mean(str2num(row));
    k = k+1;
end
fclose(fidi);

With:

RowMeans = avg

producing:

RowMeans =
     5.0000
     2.5000
     1.5000

MATLAB: Load txt file

FID = fopen(FileName, 'r');
while ~feof(FID)
  Line = fgetl(FID);
  if ischar(Line)
    D = sscanf(Line, '%g');
    a = D(1);
    b = D(2);
    c = D(3);
    ... % The calulations here
  end
