[Trilinos-Users] How to implement matrix-free operation?

[chenliang wang]

Hi,there
Is it any possible to implement matrix-free operation to compute pcg or
any other linear iterative solver? I know FLENS and MTL4 can do this,
but we have already write full matrix version at cluster. And we want to
transplant this code into pc . We still want to use trilinos . Thanks in
advance.


Best,
