clVector.Tan Method

Overload List

#	Signature	Description
1	function Tan: TOpenCLMtxVec;	Tangens.
	└ indexed: function Tan(Index: Integer; Len: Integer): TOpenCLMtxVec;
2	function Tan(const X: TOpenCLMtxVec): TOpenCLMtxVec;	Calculate the tangens of all X object elements.
	└ indexed: function Tan(const X: TOpenCLMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Overload 1: function Tan: TOpenCLMtxVec;

Tangens.

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

Remarks:

Calculate the tangens of all caling object elements in-place.

Examples

var a: clVector;
begin
    a.CopyFromArray(TSingleArray.Create(1,-2,3,4));
    a.Tan; // Computes complex tangens
end;

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

Calculate the tangens of 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 Tan(const X: TOpenCLMtxVec): TOpenCLMtxVec;

Calculate the tangens of all X object 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 clVector.Complex properties of calling object are adjusted automatically.

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

Calculate the tangens of X object 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:

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