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.
