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; } }
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.
