How can I get residual or residual to norm from Pardiso solver?

Hi All,

Can I get residual or residual to norm directly from pardiso output? If so, which variable/parameter shall I use?

Thanks

Hello,

There is no direct ouput on pardiso. But it can easily be get by calling sparse matrix - vector product to get Ax, then sub with b.
