clMatrix.Exp2 Method

Overload List

#	Signature	Description
1	function Exp2: TOpenCLMtxVec;	Exponent base 2 (2^).
	└ indexed: function Exp2(Index: Integer; Len: Integer): TOpenCLMtxVec;
2	function Exp2(const X: TOpenCLMtxVec): TOpenCLMtxVec;	Calculate the exponent base 2 (2^) for all X elements.
	└ indexed: function Exp2(const X: TOpenCLMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Overload 1: function Exp2: TOpenCLMtxVec;

Exponent base 2 (2^).

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

Remarks:

Calculate the exponent base 2 (2^) for all calling object elements in-place.

Examples

var a: clMatrix;
begin
    a.CopyFromArray(2,2,TSingleArray.Create(1,2,3,4));  // a = [1,2,3,4]
    a.Exp2;   // a = [1,4,9,16]
end;

Indexed: function Exp2(Index: Integer; Len: Integer): TOpenCLMtxVec;

Calculate the exponent base 2 (2^) for calling object elements [Index]..[Index+Len-1] in-place.

#	Name	Type	Description
1	Index	Integer	start index
2	Len	Integer	element count

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

Remarks:

An exception is raised if array borders are overrun.

Overload 2: function Exp2(const X: TOpenCLMtxVec): TOpenCLMtxVec;

Calculate the exponent base 2 (2^) for all X elements.

#	Name	Type	Description
1	X	TOpenCLMtxVec

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

Remarks:

Store the results in the calling object. Size and clMatrix.Complex properties of the calling vector are set implicitly to match the X object.

Indexed: function Exp2(const X: TOpenCLMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Calculate the exponent base 2 (2^) for X elements [XIndex]..[XIndex+Len-1].

#	Name	Type	Description
1	X	TOpenCLMtxVec
2	XIndex	Integer	X start index
3	Index	Integer	start index
4	Len	Integer	element count

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

Remarks:

Store the results in the calling object elements [Index]..[Index+Len-1]. Size and clMatrix.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
