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
◆ 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.
◆ deepcopy()
|
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.
◆ save_data_state()
|
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:
