procedure SparseToBanded(const Dst: TMtx; MaxElemCount: Integer);
Convert sparse matrix to banded matrix.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Dst | TMtx | |
| 2 | MaxElemCount | Integer |
Result: stored in self (calling object)
Remarks:
Convert calling matrix, stored in HB sparse matrix format, to banded matrix format. The result (banded matrix format) is stored in Dst matrix. The size and complex properties of Dst matrix are adjusted automatically.
Examples
var subDiag, SupDiag,MainDiag: Vector;
A: Matrix;
begin
SubDiag.Size(4);
SuperDiag.Size(4);
MainDiag.Size(4);
A.Size(3,4);
A.SubDiag := 1; // one subdiagonal
A.SuperDiag := 1; // one superdiagonal
SubDiag.SetIt([0,1,3,2]);
SupDiag.SetIt([-1,2,7,0]);
MainDiag.SetIt([2,3,5,1]);
A.SetRow(SupDiag,0);
A.SetRow(MainDiag,1);
A.SetRow(SubDiag,2);
end;SparseA.BandedToSparse(A);
