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 sc::SCMatrixRectSubBlock::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'.
