Detailed Description

The SCMatrixDiagSubBlock describes a diagonal subblock of a matrix.

The following bit of code illustrates the data layout: fill(double **matrix, SCMatrixDiagSubBlock &b) { int i,j,offset=b.offset; for (i=b.istart,j=b.jstart; i<b.iend; i++,j++,offset++) { matrix[i][j] = b.data[offset]; } }

Member Function Documentation

void sc::SCMatrixDiagSubBlock::process (SCElementOp *) [virtual]

Implements sc::SCMatrixBlock.

void sc::SCMatrixDiagSubBlock::process (SCElementOp2 *, SCMatrixBlock *) [virtual]

Implements sc::SCMatrixBlock.

void sc::SCMatrixDiagSubBlock::process (SCElementOp3 *, SCMatrixBlock *, SCMatrixBlock *) [virtual]

Implements sc::SCMatrixBlock.

void sc::SCMatrixDiagSubBlock::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.
