TOpenCLVector.UpSample Method

Overload List

#	Signature	Description
1	function UpSample(const Src: TOpenCLMtxVec; Factor: Integer; Phase: Integer): TOpenCLVector;	Inserts zeroes between consecutive vector values.
2	function UpSample(const Src: TOpenCLMtxVec; Factor: Integer; SrcIndex: Integer; Index: Integer; Len: Integer; Phase: Integer): TOpenCLMtxVec;	Inserts zeroes between consecutive array values.

Overload 1: function UpSample(const Src: TOpenCLMtxVec; Factor: Integer; Phase: Integer): TOpenCLVector;

Inserts zeroes between consecutive vector values.

#	Name	Type
1	Src	TOpenCLMtxVec
2	Factor	Integer
3	Phase	Integer

Returns: TOpenCLVector

Remarks:

Inserts zeroes between consecutive vector values. The method copies the values from Src to the calling vector and places Factor-1 zeros between consecutive values. The TOpenCLBase.Length and TOpenCLBase.Complex properties of the calling vector are set implicitly. Phase parameter defines the initial sample offset and must be less than Factor.

Examples

var a,b: TOpenCLVector;
begin
    clMtxVec.CreateIt(a,b);
    try
        b.CopyFromArray(TSingleArray.Create(0,0,1,3,2));
        a.UpSample(b,2); // a = [0,0,0,0,1,0,3,0,2,0]
    finally
        clMtxVec.FreeIt(a,b);
    end;
end;

Overload 2: function UpSample(const Src: TOpenCLMtxVec; Factor: Integer; SrcIndex: Integer; Index: Integer; Len: Integer; Phase: Integer): TOpenCLMtxVec;

Inserts zeroes between consecutive array values.

#	Name	Type	Description
1	Src	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix
2	Factor	Integer
3	SrcIndex	Integer	source start index
4	Index	Integer	start index
5	Len	Integer	element count
6	Phase	Integer

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

Remarks:

Copy Len values from Src starting at SrcIndex to the calling object starting at position Index and place Factor-1 zeros between consecutive values. Size and TOpenCLBase.Complex properties of the calling object must be set explicitly. Phase parameter defines the initial sample offset and must be less then Factor. An exception is raised, if array borders are overrun/underrun.
