### Can convergence criterion be specified?

Posted:

**Wed Mar 21, 2012 2:02 am**In CULASparseReferenceManual, "Unless otherwise specified, all of CULA Sparse’s iteration calculations are done with regards to a residual relative to

the norm of the right hand side of the linear system."

I want to know that can users specify the convergence criterion? For example, can I change this criterion to that the maximum absolute value of the change of x is less than a predefined value and how? Many thanks!
