clMatrix.ArcTan Method

Overload List

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

Overload 1: function ArcTan: TOpenCLMtxVec;

Inverse tangens.

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

Remarks:

Calculate the inverse tangens for all calling object elements in-place. The return values are expressed in radians.

Examples

var A,B: clMatrix;
begin
    A.CopyCplxFromArray(2,2,TSingleArray.Create(1,0, 2,0
        2,0  4,1));  // 2x2, complex matrix
    B.ArcTan(A);
end;

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

Calculate the inverse 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 ArcTan(const X: TOpenCLMtxVec): TOpenCLMtxVec;

Calculate the inverse 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 clMatrix.Complex properties of calling object are adjusted automatically.

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

Calculate the inverse 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 clMatrix.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
