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

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

#	Name	Type	Description
1	Vec	TMtxVec	source TVec or TMtx
2	LTLevel	Double	scalar
3	LTValue	TCplx	scalar

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

Remarks:

Store the results in calling object. Size and TMtxVec.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; const LTLevel: Double; const 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].

#	Name	Type	Description
1	Vec	TMtxVec	source TVec or TMtx
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:

Store the results in the calling object elements [Index]..[Index+Len-1]. Size and TMtxVec.Complex properties of the calling object must be set explicitly. An exception is raised if TMtxVecBase.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; const LTLevel: Double; const LTValue: Double): TMtxVec;

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

#	Name	Type	Description
1	Vec	TMtxVec	source TVec or TMtx
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 TMtxVec.Complex properties of the calling object are adjusted automatically.

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

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

#	Name	Type	Description
1	Vec	TMtxVec	source TVec or TMtx
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 TMtxVec.Complex properties of the calling object must be set explicitly. An exception is raised if TMtxVecBase.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(const LTLevel: Double; const 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(const LTLevel: Double; const 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(const LTLevel: Double; const 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 a 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: Matrix;
begin
    a.SetIt(1,2,True,[2,0.1,3,4]);
    a.ThresholdLT(2.3,1.5); // a = [1.5,1.5,3,4]
end;

Indexed: function ThresholdLT(const LTLevel: Double; const 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.
