TOpenCLMatrix.RealPart Method

function RealPart(const Vec: TOpenCLMtxVec): TOpenCLMtxVec;

Gets real part of complex object values.

#	Name	Type	Description
1	Vec	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix

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

Remarks:

The method method gets the real part of a complex object Vec and stores the real results in the calling object. Size and TOpenCLBase.Complex properties of the calling object are set implicitly to match Vec object. Vec TOpenCLBase.Complex property must be true otherwise an exception is raised.

Examples

var a,b: clMatrix;
begin
    a.CopyCplxFromArray(1,2,TSingleArray.Create(1,2,3,4)); // = [1+2i, 3+4i]
    b.RealPart(a); // b = [1,3]
end;

Indexed: function RealPart(const Vec: TOpenCLMtxVec; VecIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Gets the real part of a Vec object complex elements [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix
2	VecIndex	Integer
3	Index	Integer	start index
4	Len	Integer	element count

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

Remarks:

Stores the results in calling object real elements [Index]..[Index+Len-1]. An exception is raised if array borders are overrun or underrun or if Vec object TOpenCLBase.Complex propety is false.
