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

Perform "less than" threshold operation for complex numbers on all Vec object values and store the results in calling object.

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

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

Remarks:

Size and Vector.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: TMtxVec; LTLevel: Double; LTValue: TCplx; VecIndex: Integer; Index: Integer; Len: Integer): TMtxVec;

Perform "less than" threshold operation for complex numbers on Vec elements from range [VecIndex]..[VecIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1].

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

Size and Vector.Complex properties of the calling object must be set explicitly. An exception is raised if Vector.ConditionCheck is true and 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: TMtxVec; LTLevel: Double; LTValue: Double): TMtxVec;

Perform "less than" threshold operation on all Vec object values and store the results in calling object.

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

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

Remarks:

Size and Vector.Complex properties of the calling object are adjusted automatically.

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

Perform "less than" threshold operation on Vec elements from range [VecIndex]..[VecIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	Vec	TMtxVec
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:

Size and Vector.Complex properties of the calling object must be set explicitly. An exception is raised if Vector.ConditionCheck is true and 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; LTValue: TCplx): TMtxVec;

Perfrom "less than" threshold operation for complex numbers.

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

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; LTValue: TCplx; Index: Integer; Len: Integer): TMtxVec;

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

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

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: Vector;
begin
    a.SetIt(True,[2,0.1,3,4]);
    a.ThresholdLT(2.3,1.5); // a = [1.5,1.5,3,4]
end;

Indexed: function ThresholdLT(LTLevel: Double; LTValue: Double; Index: Integer; Len: Integer): TMtxVec;

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

#	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.
