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.

    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.

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.
