function DownSample(const Src: TOpenCLMtxVec; Factor: Integer; SrcIndex: Integer; Index: Integer; Len: Integer; Phase: Integer): TOpenCLMtxVec;
Downsamples object 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 only every Factor sample from Src starting at SrcIndex up to Len to the calling object starting at Index. The phase parameter determines the initial sample offset. Phase must be less then Factor. Size and TOpenCLBase.Complex properties of the calling object are set implicitly. An exception is raised if array borders are overrun/underrun.
