TOpenCLVector.Ln Method

Overload List

#	Signature	Description
1	TOpenCLMtxVec Ln	Natural logarithm.
	└ indexed: TOpenCLMtxVec Ln(Int32 Index, Int32 Len)
2	TOpenCLMtxVec Ln(TOpenCLMtxVec X)	Calculate the natural algorithm for all X elements.
	└ indexed: TOpenCLMtxVec Ln(TOpenCLMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Overload 1: TOpenCLMtxVec Ln

Natural logarithm.

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

Remarks:

Calculate the natural log for all calling object elements in-place.

Examples

clVector A;
clVector B;
A.CopyFromArray(TSingleArray.Create(1,2,3,4));
B.Ln(A);

Indexed: TOpenCLMtxVec Ln(Int32 Index, Int32 Len)

Calculate the natural logarithm for 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 Ln(TOpenCLMtxVec X)

Calculate the natural algorithm for all X 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 Dew.Math.TOpenCLBase.Complex properties of the calling vector are set implicitly to match the X object.

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

Calculate the natural logarithm for X 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:

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