Detailed Description

template<class Vector>
class Opm::MixedMatrixWrapper< Vector >

Wraps c-implementation of mixed-precision matrix.

Note

matrix is stored in single precision, but all operations are performed in double-precision

Template Parameters

Vector	the block-vector used by linear operator
b	block size
