Detailed Description

template<class MatrixType>
class Foam::MatrixBlock< MatrixType >

A templated block of an (m x n) matrix of type <MatrixType>.

Foam::ConstMatrixBlock: block of a const matrix Foam::MatrixBlock: block of a non-const matrix

The block may be assigned to a block of another matrix or to a VectorSpace or MatrixSpace e.g. tensor. Conversion of a column block to a Field<T> is also provide.
