Detailed Description

The SCMatrixRectBlock describes a rectangular piece of a matrix.

The following bit of code illustrates the data layout: fill(double **matrix, SCMatrixRectBlock &b) { int offset=0; 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]; } } }

Member Function Documentation

double* SCMatrixRectBlock::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 SCMatrixBlock.

SCMatrixBlock* SCMatrixRectBlock::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 SCMatrixBlock.

void SCMatrixRectBlock::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.
