I am working with the package Trilinos, in particular with the Epetra part of Trilinos. I am making computations with Epetra_CRSMatrices, but I could not find any mathematical functions for these matrices. In particular I need to compute the transpose and the inverse of an Epetra_CRSMatrix, to calculate the product of two Epetra_CRSMatrices, and the product of an Epetra_CRSMatrix with an Epetra_Vector. Does there exist any standard functions for these operations? I checked the functions of the above mentioned classes but I found nothing.
