TOpenCLVector.Sign Method

Overload List

#	Signature	Description
1	TOpenCLMtxVec Sign	Changes elements sign.
	└ indexed: TOpenCLMtxVec Sign(Int32 Index, Int32 Len)
2	TOpenCLMtxVec Sign(TOpenCLMtxVec X)	Change all X object elements sign.
	└ indexed: TOpenCLMtxVec Sign(TOpenCLMtxVec X, Int32 XIndex, Int32 Index, Int32 Len)

Changes elements sign.

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

Remarks:

Changes all calling object elements sign (v -> -v) in-place.

Examples

clVector a;
a.CopyFromArray(TSingleArray.Create(1,2,-3,4));
a.Sign; // a = new double[] {-1,-2,3,-4}

Change calling object elements [Index]..[Index+Len-1] sign 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 or underrun.

Change all X object elements sign.

#	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 calling object. Size and Dew.Math.TOpenCLBase.Complex properties of calling object are adjusted automatically.

Change X object elements [XIndex]..[XIndex+Len-1] sign.

#	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 callingobject elements [Index]..[Index+Len-1]. An exception is raised if array borders are overrun or underrun.
