conjugate gradient method for linear equations
Does any one know the ratio in conjugate gradient method for linear equations system? My error is the ratio is either NAN or too low (e-15). Then how do I adjust the syetem of eqations to get correct solution?

Re: conjugate gradient method for linear equations
I reccomend you to use Saad's package SPARSKIT
http://www-users.cs.umn.edu/~saad/so.../sparskit.html I use conjugate gradient solver from it and it works well. Look. I think it will help you. I wish good luck. |
