.SH "Detailed Description"
.PP 
The \fBSCMatrixDiagBlock\fP 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]; } }

.PP 
.SS "double* sc::SCMatrixDiagBlock::dat ()\fC [virtual]\fP"

.PP
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\&. 
.PP
Reimplemented from \fBsc::SCMatrixBlock\fP\&.
.SS "\fBSCMatrixBlock\fP* sc::SCMatrixDiagBlock::deepcopy () const\fC [virtual]\fP"

.PP
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\&. 
.PP
Reimplemented from \fBsc::SCMatrixBlock\fP\&.
.SS "void sc::SCMatrixDiagBlock::save_data_state (\fBStateOut\fP &)\fC [virtual]\fP"

.PP
Save the base classes (with save_data_state) and the members in the same order that the \fBStateIn\fP CTOR initializes them\&. This must be implemented by the derived class if the class has data\&. 
.PP
Reimplemented from \fBsc::SCMatrixBlock\fP\&.
