Detailed Description

The SCMatrixRectSubBlock describes a rectangular piece of a matrix.

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

Member Function Documentation

void SCMatrixRectSubBlock::save_data_state ( StateOut & s ) [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 SCMatrixBlock.
