TOpenCLMatrix.ThreshTop Method

Overload List

#	Signature	Description
1	function ThreshTop(const Src: TOpenCLMtxVec; const Value: Double): TOpenCLMtxVec;	Perform threshold operation on all Src object values.
	└ indexed: function ThreshTop(const Vec: TOpenCLMtxVec; const Value: Double; VecIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;
2	function ThreshTop(const Value: Double): TOpenCLMtxVec;	Threshold top operation.
	└ indexed: function ThreshTop(const Value: Double; Index: Integer; Len: Integer): TOpenCLMtxVec;

Overload 1: function ThreshTop(const Src: TOpenCLMtxVec; const Value: Double): TOpenCLMtxVec;

Perform threshold operation on all Src object values.

#	Name	Type	Description
1	Src	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix
2	Value	Double	scalar

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

Remarks:

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

Indexed: function ThreshTop(const Vec: TOpenCLMtxVec; const Value: Double; VecIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Perform a threshold operation Vec elements [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TOpenCLMtxVec	source TOpenCLVector or TOpenCLMatrix
2	Value	Double	scalar
3	VecIndex	Integer
4	Index	Integer	start index
5	Len	Integer	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 TOpenCLBase.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun/underrun.

Overload 2: function ThreshTop(const Value: Double): TOpenCLMtxVec;

Threshold top operation.

#	Name	Type	Description
1	Value	Double	scalar

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

Remarks:

Perform threshold operation on all calling object values. The Value parameter is an upper bound for threshold operation. All values bigger than Value will be replaced with Value.

Examples

var a: clMatrix;
begin
    a.CopyFromArray(2,2,TSingleArray.Create(2,0.1,3,4));
    a.Threshtop(0.2); // a = [0.2,0.1,0.2,0.2]
end;

Indexed: function ThreshTop(const Value: Double; Index: Integer; Len: Integer): TOpenCLMtxVec;

Perfrom the threshold operation on calling object values [Index]..[Index+Len-1].

#	Name	Type	Description
1	Value	Double	scalar
2	Index	Integer	start index
3	Len	Integer	element count

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

Remarks:

An exception is raised if array borders are overrun/underrun.
