  *  \brief implement a solver for a set of linear equations.
  *
  *   LSQR  finds a solution x to the following problems:
- *  
+ *
  *   1. Unsymmetric equations:    Solve  A*x = b
- *  
+ *
  *   2. Linear least squares:     Solve  A*x = b
  *                                in the least-squares sense
- *  
+ *
  *   3. Damped least squares:     Solve  (   A    )*x = ( b )
  *                                       ( damp*I )     ( 0 )
  *                                in the least-squares sense
- *  
+ *
  *   where A is a matrix with m rows and n columns, b is an m-vector,
  *   and damp is a scalar.  (All quantities are real.)
  *   The matrix A is treated as a linear operator.  It is accessed
  *   by means of subroutine calls with the following purpose:
- *  
+ *
  *   call Aprod1(m,n,x,y)  must compute y = y + A*x  without altering x.
  *   call Aprod2(m,n,x,y)  must compute x = x + A'*y without altering y.
- *  
+ *
  *   LSQR uses an iterative method to approximate the solution.
  *   The number of iterations required to reach a certain accuracy
  *   depends strongly on the scaling of the problem.  Poor scaling of
  *   the rows or columns of A should therefore be avoided where
  *   possible.
- *  
+ *
  *   For example, in problem 1 the solution is unaltered by
  *   row-scaling.  If a row of A is very small or large compared to
  *   the other rows of A, the corresponding row of ( A  b ) should be
  *   scaled up or down.
- *  
+ *
  *   In problems 1 and 2, the solution x is easily recovered
  *   following column-scaling.  Unless better information is known,
  *   the nonzero columns of A should be scaled so that they all have
  *   the same Euclidean norm (e.g., 1.0).
- *  
+ *
  *   In problem 3, there is no freedom to re-scale if damp is
  *   nonzero.  However, the value of damp should be assigned only
  *   after attention has been paid to the scaling of A.
- *  
+ *
  *   The parameter damp is intended to help regularize
  *   ill-conditioned systems, by preventing the true solution from
  *   being very large.  Another aid to regularization is provided by
