These functions are used to get timings from class internal computations.

The values are stored in a user defined concepts::InOutParameters structure in different arrays (see setTimings). These arrays can be grouped into a table for easier postprocessing with

    concepts::ResultsTable table;
    table.addMap(concepts::ResultsTable::DOUBLE, "jacobian", output);
    table.addMap(concepts::ResultsTable::DOUBLE, "whole_sumfact", output);

static void concepts::Matrix< F >::assembly ( Matrix< F > &  dest,
const Space< G > &  spc,
BilinearForm< F, G > &  bf,
const Real  threshold = 0.0 
) [static]

Assembly operator for dest using the bilinear form bf.

This assembly operator does not compute element matrices for two different elements. The elements are taken from the space spc.

Examples:
linearDG1d.cc.

static void concepts::Matrix< F >::assembly ( Matrix< F > &  dest,
const Space< G > &  spcX,
const Space< G > &  spcY,
BilinearForm< F, G > &  bf,
const Real  threshold = 0.0 
) [static]

Assembly operator for dest using the bilinear form bf.

This assembly operator computes also the element matrices for two different elements (coming from spcX and spcY).

template<class G >
static void concepts::Matrix< F >::assembly ( Matrix< F > &  dest,
BilinearForm< F, G > &  bf,
const ElementPairList< G > &  pairs 
) [static]

Assembly operator for dest using the bilinear form bf.

This assembly operator uses the element pairs taken from pairs. For every two elements found in a ElementPair in pairs, the bilinear form is evaluated and the result assembled into dest.

template<class F>

template<class F>
virtual void concepts::Matrix< F >::operator() ( const Function< c_type > &  fncY,
Function< c_type > &  fncX 
) [pure virtual]

Application operator for complex function fncY.

Computes fncX = A(fncY) where A is this operator. fncX becomes complex.

In derived classes its enough to implement the operator() for complex Operator's. If a real counterpart is not implemented, the function fncY is splitted into real and imaginary part and the application operator for real functions is called for each. Then the result is combined.

If in a derived class the operator() for complex Operator's is not implemented, a exception is thrown from here.

Reimplemented from concepts::Operator< F >.

Implemented in concepts::DenseMatrix< F >, concepts::DiagonalMatrix< F >, concepts::Permutation< F >, concepts::SparseMatrix< F >, concepts::SubMatrixN< F >, concepts::Transpose< F >, concepts::DenseMatrix< Cmplx >, concepts::DenseMatrix< Real >, concepts::DiagonalMatrix< Real >, concepts::Permutation< Real >, concepts::SparseMatrix< concepts::Real >, concepts::SparseMatrix< FX >, concepts::SparseMatrix< T >, concepts::SparseMatrix< Cmplx >, and concepts::SparseMatrix< Real >.

static void concepts::Matrix< F >::setTimings ( InOutParameters timings) [static]

Sets the class to store the timing values in.

Additionally, the timeCntr_ is reset to 0. This counter is used to fill in the values into the arrays listed below in subsequent calls. The following timings are taken and stored in timings:

  • evaluation of bilinear form in bilinear_form
  • application of T matrix in tmatrix_apply
  • assembling into global matrix in global_assembly
template<class F>
static bool concepts::Matrix< F >::timings ( ) [static]

Returns true if the class is able to do timings.

The ability to do timings depends on a compiler switch in matrix.cc file.
