MatrixInt.CopyVec Method

Overload List

#	Signature	Description
1	function CopyVec(const Vec: TVecInt; NrRows: Integer): TMtxInt;	Copies values from vector to a matrix.
2	function CopyVec(const Vec: TVecInt; VecIndex: Integer; Len: Integer; Row: Integer; Col: Integer): TMtxInt;	Copy Vec elements [VecIndex]..[VecIndex+Len-1] to the calling matrix elements starting with [Row,Col].

Overload 1: function CopyVec(const Vec: TVecInt; NrRows: Integer): TMtxInt;

Copies values from vector to a matrix.

#	Name	Type	Description
1	Vec	TVecInt
2	NrRows	Integer

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

Remarks:

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

Examples

var A: MatrixInt;
    v: VectorInt;
begin
    Create(v);
    v := [1,0,2,-1,5,1.2];
    A.CopyVec(v);
end;

Overload 2: function CopyVec(const Vec: TVecInt; VecIndex: Integer; Len: Integer; Row: Integer; Col: Integer): TMtxInt;

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

#	Name	Type	Description
1	Vec	TVecInt
2	VecIndex	Integer
3	Len	Integer	element count
4	Row	Integer
5	Col	Integer

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

Remarks:

An exception is raised if TMtxVecBase.ConditionCheck is true and bounds are overrun or if TMtxVecInt.IntPrecision properties of the calling matrix and Vec do not match.
