Detailed Description

The SCMatrixDiagBlock describes a diagonal piece of a matrix.

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.
