I have cosulted the MATLAB document for lsqr. It is a function to solve linear 
relation Ax=b in iterative least square method. It is intended for A being a 
large sparse matrix.

Now MATLAB and octave can handle sparse matrices in sophisticated way so that 
x=A\b works in most case even if A is a large sparse matrix.
