TOpenCLMatrix.Cot Method

Overload List

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

Overload 1: function Cot: TOpenCLMtxVec;

Cotangens.

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

Remarks:

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

Examples

var a: clMatrix;
begin
    a.CopyFromArray(2,2,TSingleArray.Create(1,-2,3,4));
    a.Cot; // Computes complex cotangens
end;

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

Calculate the cotangens 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 Cot(const X: TOpenCLMtxVec): TOpenCLMtxVec;

Calculate the cotangens of all X object elements.

#	Name	Type	Description
1	X	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix

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

Remarks:

Store the results in the calling object. Size and TOpenCLBase.Complex properties of calling object are adjusted automatically.

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

Calculate the cotangens of X object elements [XIndex]...[XIndex+Len-1].

#	Name	Type	Description
1	X	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix
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 TOpenCLBase.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
