The following bit of code illustrates the data layout: fill(double **matrix, SCMatrixDiagBlock &b) { int i,j,offset=0; for (i=b.istart,j=b.jstart; i<b.iend; i++,j++,offset++) { matrix[i][j] = b.data[offset]; } } Member Function Documentation double* sc::SCMatrixDiagBlock::dat (    )  [virtual]   Return a pointer to the block's data and the number of elements in the block. Some blocks cannot provide this information and a runtime error will be generated if these members are called. These routines are only used internally in the matrix library. Reimplemented from sc::SCMatrixBlock. SCMatrixBlock* sc::SCMatrixDiagBlock::deepcopy (    )  const [virtual]   Return of copy of this. A runtime error will be generated for blocks that cannot do a deepcopy. These routines are only used internally in the matrix library. Reimplemented from sc::SCMatrixBlock. void sc::SCMatrixDiagBlock::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. The documentation for this class was generated from the following file: block.h
