Detailed Description

The SCMatrixLTriSubBlock describes a triangular subblock of a matrix.

The following bit of code illustrates the data layout: fill(double **matrix, SCMatrixLTriSubBlock &b) { int offset=(b.istart*(b.istart+1)>>1) + b.jstart; for (int i=b.start; i<b.end; i++) { for (int j=b.start; j<=i && j<b.jend; j++,offset++) { matrix[i][j] = b.data[offset]; } if (j>i) offset += b.istart; else offset += i + b.jstart - b.jend; } }

Member Function Documentation

process() [1/3]

void sc::SCMatrixLTriSubBlock::process ( SCElementOp * )

virtual

Implements sc::SCMatrixBlock.

process() [2/3]

void sc::SCMatrixLTriSubBlock::process ( SCElementOp2 * , SCMatrixBlock *  )

virtual

Implements sc::SCMatrixBlock.

process() [3/3]

void sc::SCMatrixLTriSubBlock::process ( SCElementOp3 * , SCMatrixBlock * , SCMatrixBlock *  )

virtual

Implements sc::SCMatrixBlock.

save_data_state()

void sc::SCMatrixLTriSubBlock::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.
