Class to hold temporary vectors. This class automatically allocates a new vector, once it is needed.
A future version should also be able to shift through vectors automatically, avoiding restart.

internal::SolverGMRESImplementation::TmpVectors< VectorType >::TmpVectors | ( | const unsigned int | max_size, |
VectorMemory< VectorType > & | vmem ) |
Constructor. Prepares an array of VectorType
of length max_size
.
|
default |
Destructor. Delete all allocated vectors.
VectorType & internal::SolverGMRESImplementation::TmpVectors< VectorType >::operator[] | ( | const unsigned int | i | ) | const |
Get vector number i
. If this vector was unused before, an error occurs.
VectorType & internal::SolverGMRESImplementation::TmpVectors< VectorType >::operator() | ( | const unsigned int | i, |
const VectorType & | temp ) |
Get vector number i
. Allocate it if necessary.
If a vector must be allocated, temp
is used to reinit it to the proper dimensions.
unsigned int internal::SolverGMRESImplementation::TmpVectors< VectorType >::size | ( | ) | const |
Return size of data vector. It is used in the solver to store the Arnoldi vectors.
