<div dir="ltr"><div><div><div>Hi all,<br><br></div><div>For example, I am using LSQR or CG to solve Ax=b.<br></div><div><br></div>When we turn on the monitor option of solving the linear system, we could see iteration number and residual for each iteration. I believe it's L2 norm of the objective function?<br><br></div>If yes, is there a way that I could set it to L1 norm for solving the system?<br><br></div>Thanks.<br clear="all"><div><div><div><div><div><div><br>-- <br>Brian Yang<br>U of Houston<br><br><br><br>
