Overload 1: function ThresholdLT(const Vec: TOpenCLMtxVec; LTLevel: Double; const LTValue: TCplx): TOpenCLMtxVec;

Perform "less than" threshold operation for complex numbers on all Vec object values.

#	Name	Type	Description
1	Vec	TOpenCLMtxVec
2	LTLevel	Double	scalar
3	LTValue	TCplx

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

Remarks:

Store the results in calling object. Size and clVector.Complex properties of the calling object are adjusted automatically. If Vec object contains none Complex values, an exception will be raised.

Indexed: function ThresholdLT(const Vec: TOpenCLMtxVec; LTLevel: Double; const LTValue: TCplx; VecIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Perform "less than" threshold operation for complex numbers on Vec elements from range [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TOpenCLMtxVec
2	LTLevel	Double	scalar
3	LTValue	TCplx
4	VecIndex	Integer
5	Index	Integer	start index
6	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 clVector.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun/underrun. If Vec object or calling object contain none Complex values, an exception will be raised.

Overload 2: function ThresholdLT(const Vec: TOpenCLMtxVec; LTLevel: Double; LTValue: Double): TOpenCLMtxVec;

Perform "less than" threshold operation on all Vec object values.

#	Name	Type	Description
1	Vec	TOpenCLMtxVec
2	LTLevel	Double	scalar
3	LTValue	Double	scalar

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

Remarks:

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

Indexed: function ThresholdLT(const Vec: TOpenCLMtxVec; LTLevel: Double; LTValue: Double; VecIndex: Integer; Index: Integer; Len: Integer): TOpenCLMtxVec;

Perform "less than" threshold operation on Vec elements from range [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Vec	TOpenCLMtxVec
2	LTLevel	Double	scalar
3	LTValue	Double	scalar
4	VecIndex	Integer
5	Index	Integer	start index
6	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 clVector.Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun/underrun. An exception will be raised if Vec.Complex and Complex of the calling object are not equal.

Overload 3: function ThresholdLT(LTLevel: Double; const LTValue: TCplx): TOpenCLMtxVec;

Perfrom "less than" threshold operation for complex numbers.

#	Name	Type	Description
1	LTLevel	Double	scalar
2	LTValue	TCplx

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

Remarks:

If the calling object contains none Complex values, an exception will be raised.

Indexed: function ThresholdLT(LTLevel: Double; const LTValue: TCplx; Index: Integer; Len: Integer): TOpenCLMtxVec;

Perfrom "less than" threshold operation for complex numbers on the calling object values in range [Index]..[Index+Len-1].

#	Name	Type	Description
1	LTLevel	Double	scalar
2	LTValue	TCplx
3	Index	Integer	start index
4	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. If the calling object contains none Complex values, an exception will be raised.

Overload 4: function ThresholdLT(LTLevel: Double; LTValue: Double): TOpenCLMtxVec;

Threshold less than operation.

#	Name	Type	Description
1	LTLevel	Double	scalar
2	LTValue	Double	scalar

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

Remarks:

Perform operation on all calling object values. The LTValue parameter is an lower bound for threshold operation. All values less than LTLevel will be replaced with LTValue. For complex number comparation is applied with norm of complex value.

Examples

var a: clVector;
begin
    a.CopyFromArray(TSingleArray.Create(2,0.1,3,4));
    a.ThresholdLT(2.3,1.5); // a = [1.5,1.5,3,4]
end;

#	Name	Type	Description
1	LTLevel	Double	scalar
2	LTValue	Double	scalar
3	Index	Integer	start index
4	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.
