TSparseMtx.AddSplit Method

Overload List

#	Signature	Description
1	void AddSplit(TSparseMtx LowerTriang, TSparseMtx UpperTriang)	Sums up the sparse matrix from its lower (LoweTriang) and upper triangle (UpperTriang).
2	void AddSplit(TSparseMtx LowerTriang, TVec Diag, TSparseMtx UpperTriang)	Construct sparse matrxix by summing lower, upper triangluar part and the diagonal.

Overload 1: void AddSplit(TSparseMtx LowerTriang, TSparseMtx UpperTriang)

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: void AddSplit(TSparseMtx LowerTriang, TVec Diag, TSparseMtx UpperTriang)

Construct sparse matrxix by summing lower, upper triangluar part and the diagonal.

#	Name	Type	Description
1	LowerTriang	TSparseMtx
2	Diag	TVec	source 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

    private void Example()
    {
        Vector d = new Vector(0);
        TSparseMtx asp = new TSparseMtx();
        TSparseMtx bsp = new TSparseMtx();
        TSparseMtx csp = new TSparseMtx();
        TSparseMtx dsp = new TSparseMtx();
        // ...
        // #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);
    }
