Detailed Description

This class is a base class for matrices that can be used in petsc::KrylovSolver.

Member Function Documentation

create_vector()

Vec create_vector

(

std::size_t

dim

)

const

Initialize vector to be compatible with the matrix-vector product y = Ax. In the parallel case, size and layout are both important.

Parameters

[in]

dim

The dimension (axis): dim = 0 --> z = y, dim = 1 --> z = x

size()

std::array< std::int64_t, 2 > size

(

)

const

Return number of rows and columns (num_rows, num_cols). PETSc returns -1 if size has not been set.
