TMtx.CopyVec Method

Overload List

#	Signature	Description
1	TMtx CopyVec(TVec Vec, Int32 NrRows)	Copies values from vector to a matrix.
2	TMtx CopyVec(TVec Vec, Int32 VecIndex, Int32 Len, Int32 Row, Int32 Col)	Copy Vec elements [VecIndex]..[VecIndex+Len-1] to the calling matrix elements starting with [Row,Col].

Overload 1: TMtx CopyVec(TVec Vec, Int32 NrRows)

Copies values from vector to a matrix.

#	Name	Type	Description
1	Vec	TVec	source TVec
2	NrRows	Int32

Result: stored in self (calling object), returns self for chaining

Remarks:

Copy all Vec elements to the calling matrix. Set the calling matrix Dew.Math.TMtx.Rows property to NrRows. Set the calling matrix Dew.Math.TMtx.Cols property to Vec.Length div NrRow (Length = Rows*Cols). The calling matrix Dew.Math.TMtxVec.Complex property is adjusted automatically. An exception is raised if Vec.Length mod NrRows <> 0.

Examples

TMtx A;
TVec v;
MtxVec.CreateIt(out A);
Create(v);
try
    {
        v.SetIt(true,new double[] {1, 0, 2, -1, 5, 1.2}) ;
        A.CopyVec(v);
    }
finally
    {
        MtxVec.FreeIt(ref A);
    }

Overload 2: TMtx CopyVec(TVec Vec, Int32 VecIndex, Int32 Len, Int32 Row, Int32 Col)

Copy Vec elements [VecIndex]..[VecIndex+Len-1] to the calling matrix elements starting with [Row,Col].

#	Name	Type	Description
1	Vec	TVec	source TVec
2	VecIndex	Int32
3	Len	Int32	element count
4	Row	Int32
5	Col	Int32

Result: stored in self (calling object), returns self for chaining

Remarks:

An exception is raised if Dew.Math.TMtxVecBase.ConditionCheck is true and bounds are overrun or if Dew.Math.TMtxVec.Complex properties of the calling matrix and Vec do not match.
