clVector.Cos Method

Overload List

#	Signature	Description
1	TOpenCLMtxVec Cos	Cosine.
	└ indexed: TOpenCLMtxVec Cos(Int32 Index, Int32 Len)
2	TOpenCLMtxVec Cos(TOpenCLMtxVec X)	Calculate the cosine of all X object elements.
	└ indexed: TOpenCLMtxVec Cos(TOpenCLMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Overload 1: TOpenCLMtxVec Cos

Cosine.

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

Remarks:

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

Examples

clVector a;
a.CopyFromArray(TSingleArray.Create(1,-2,3,4));
a.Cos; // Computes complex sine

See Also: clVector.ArcCos, clVector.SinCos

Indexed: TOpenCLMtxVec Cos(Int32 Index, Int32 Len)

Calculate the cosine of calling object elements [Index]...[Index+Len-1] in-place.

#	Name	Type	Description
1	Index	Int32	start index
2	Len	Int32	element count

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

Remarks:

An exception is raised if array borders are overrun.

Overload 2: TOpenCLMtxVec Cos(TOpenCLMtxVec X)

Calculate the cosine 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.vSize and Dew.Math.clVector.Complex properties of calling object are adjusted automatically.

Indexed: TOpenCLMtxVec Cos(TOpenCLMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

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

#	Name	Type	Description
1	X	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix
2	XIndex	Int32	X start index
3	Index	Int32	start index
4	Len	Int32	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 Dew.Math.clVector.Complex properties of calling object and the calling object must be set explicitly. An exception is raised if array borders are overrun.
