What about a scaled_norm of sorts where you can weight each variable by a constant?
Yours is then just a special case with a one and some zeros? ----- Original Message ----- From: Derek Gaston <[EMAIL PROTECTED]> To: [email protected] <[email protected]> Sent: Wed Nov 05 16:08:09 2008 Subject: [Libmesh-users] Norm of a NumericVector for specific variable... Anyone have a good piece of code for computing a norm of just the piece of a NumericVector that corresponds to a specific variable number? My problem is that I have multiple variables in my system... but I need to get the norm of the residual for each one individually. Should we maybe extend the l2_norm(), l1_norm(), linfty_norm() functions to take an option variable number?
