| 1 | procedure AddSplit(const LowerTriang: TSparseMtx; const UpperTriang: TSparseMtx); | Sums up the sparse matrix from its lower (LoweTriang) and upper triangle (UpperTriang). |
| 2 | procedure AddSplit(const LowerTriang: TSparseMtx; const Diag: TVec; const UpperTriang: TSparseMtx); | Construct sparse matrxix by summing lower, upper triangluar part and the diagonal. |
Overload 1: procedure AddSplit(const LowerTriang: TSparseMtx; const UpperTriang: TSparseMtx);
Sums up the sparse matrix from its lower (LoweTriang) and upper triangle (UpperTriang).
| # | Name | Type | Description |
|---|---|---|---|
| 1 | LowerTriang | TSparseMtx | |
| 2 | UpperTriang | TSparseMtx |
Result: stored in self (calling object)
Overload 2: procedure AddSplit(const LowerTriang: TSparseMtx; const Diag: TVec; const UpperTriang: TSparseMtx);
Construct sparse matrxix by summing lower, upper triangluar part and the diagonal.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | LowerTriang | TSparseMtx | |
| 2 | Diag | TVec | |
| 3 | UpperTriang | TSparseMtx |
Result: stored in self (calling object)
Remarks:
Sums up the sparse matrix from its three parts: The lower triangle (LowerTriang), main diagonal (Diag) and upper triangle (UpperTriang).
Examples
var asp, bsp,csp, dsp: TSparseMtx;
d: Vector;
begin
// ...
// #1 : split asp into lower(bsp), upper(csp) and diagonal(d) sections
bsp.LowerTriangle(asp);
csp.UpperTriangle(asp);
asp.Diag(d);
// now combine lower(bsp), upper, and diagonal(d) back
dsp.AddSplit(bsp,d,csp);
// should be equal
if not asp.Equal(dsp) then Eraise('Not Equal!');
