[Trilinos-Users] How to implement Kronecker product and sum of two matrix in Trilinos?

[john]

Hi,
Everybody, I am now using Trilinos working on solving PDE.
I need to perform Kronecker product and sum of two crs-matrix ,
but I can't find any related modules or codes, so I must code it by myself?
Anybody have similar codes? Please give some suggestions.
