function DownSample(const Src: TOpenCLMtxVec; Factor: Integer; Phase: Integer): TOpenCLVector;
Downsamples vector values.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TOpenCLMtxVec | |
| 2 | Factor | Integer | |
| 3 | Phase | Integer |
Returns: TOpenCLVector
Remarks:
The methods copies only every Factor sample from the Src vector to the calling vector. The TOpenCLBase.Length and TOpenCLBase.Complex properties of the calling vector are set implicitly. The phase parameter determines the initial sample offset. Phase must be less than Factor.
Examples
var a,b: clVector;
begin
b.CopyFromArray(TSingleArray.Create(0,0,0,0,1,2,3,4,5,6));
a.DownSample(b,2); // a = [0,0,1,3,5]
