template<typename T, typename A, int n, int m>
class Dune::UMFPack< BCRSMatrix< FieldMatrix< T, n, m >, A > >
The UMFPack direct sparse solver for matrices of type BCRSMatrix.
Specialization for the Dune::BCRSMatrix. UMFPack will always go double precision and supports complex numbers too (use std::complex<double> for that).
- Template Parameters
-
T | Number type. Only double and std::complex<double> is supported |
A | STL-compatible allocator type |
n | Number of rows in a matrix block |
m | Number of columns in a matrix block |
- Note
- This will only work if dune-istl has been configured to use UMFPack
