| Multiplication of the transposed matrix times a vector.

The interface of our matrices is designed according to what they represent from a mathematical point of view. The vector classes are representations of vector spaces:
template<class M >
int Dune::countNonZeros |
( |
const M & |
matrix | ) |
|
|
inline |
Get the number of nonzero fields in the matrix.
This is not the number of nonzero blocks, but the number of non zero scalar entries (on blocklevel 1) if the matrix is viewed as a flat matrix.
For FieldMatrix this is simply the number of columns times the number of rows, for a BCRSMatrix<FieldMatrix<K,n,m>> this is the number of nonzero blocks time n*m.
