NAME
sc::SCMatrixDiagBlock - The SCMatrixDiagBlock describes a diagonal
piece of a matrix.
SYNOPSIS
#include <block.h> Inherits sc::SCMatrixBlock. Public Member Functions SCMatrixDiagBlock (int istart, int iend, int jstart) SCMatrixDiagBlock (int istart, int iend) SCMatrixDiagBlock (StateIn &) void save_data_state (StateOut &) Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. SCMatrixBlock * deepcopy () const Return of copy of this. void process (SCElementOp *) void process (SCElementOp2 *, SCMatrixBlock *) void process (SCElementOp3 *, SCMatrixBlock *, SCMatrixBlock *) double * dat () Return a pointer to the block's data and the number of elements in the block. int ndat () const Public Attributes int istart int jstart int iend double * data
Detailed Description
The SCMatrixDiagBlock describes a diagonal piece of a matrix.
The following bit of code illustrates the data layout: fill(double
**matrix, SCMatrixDiagBlock &b) { int i,j,offset=0; for
(i=b.istart,j=b.jstart; i<b.iend; i++,j++,offset++) { matrix[i][j] =
b.data[offset]; } }
Member Function Documentation
- void sc::SCMatrixDiagBlock::save_data_state (StateOut &) [virtual]
- Save the base classes (with save_data_state) and the members in the
same order that the StateIn CTOR initializes them. - This must be implemented by the derived class if the class has data.
- Reimplemented from sc::SCMatrixBlock.
- SCMatrixBlock* sc::SCMatrixDiagBlock::deepcopy () const [virtual]
- Return of copy of this.
- A runtime error will be generated for blocks that cannot do a deepcopy. These routines are only used internally in the matrix library.
- Reimplemented from sc::SCMatrixBlock.
- double* sc::SCMatrixDiagBlock::dat () [virtual]
- Return a pointer to the block's data and the number of elements in the block.
- Some blocks cannot provide this information and a runtime error will be
generated if these members are called. These routines are only used
internally in the matrix library. - Reimplemented from sc::SCMatrixBlock.
