TVecInt.ThreshAbsLT Method

Overload List

#	Signature	Description
1	function ThreshAbsLT(const Src: TMtxVecInt; const Value: Integer): TMtxVecInt;	Perform threshold operation on all Src object values.
	└ indexed: function ThreshAbsLT(const Vec: TMtxVecInt; const Value: Integer; VecIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;
2	function ThreshAbsLT(const Value: Integer): TMtxVecInt;	Threshold top and bottom centered around zero.
	└ indexed: function ThreshAbsLT(const Value: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Overload 1: function ThreshAbsLT(const Src: TMtxVecInt; const Value: Integer): TMtxVecInt;

Perform threshold operation on all Src object values.

#	Name	Type	Description
1	Src	TMtxVecInt	source TVecInt or TMtxInt
2	Value	Integer

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

Remarks:

Store the results in calling object. Size and TMtxVecInt.IntPrecision properties of the calling object are adjusted automatically.

Indexed: function ThreshAbsLT(const Vec: TMtxVecInt; const Value: Integer; VecIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;

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

#	Name	Type	Description
1	Vec	TMtxVecInt	source TVecInt or TMtxInt
2	Value	Integer
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 TMtxVecInt.IntPrecision properties of the calling object must be set explicitly. An exception is raised if TMtxVecBase.ConditionCheck is true and array borders are overrun/underrun.

Overload 2: function ThreshAbsLT(const Value: Integer): TMtxVecInt;

Threshold top and bottom centered around zero.

#	Name	Type	Description
1	Value	Integer

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 smaller than Value will be replaced with Value and all values bigger than -Value will be replaced with -Value. The comparison checks if abs(Values[i]) < Value.

Examples

var a: TVecInt;
begin
    CreateIt(a);
    try
        a.SetIt([2,-1,3,4]);
        a.ThreshAbsLT(2); // a = [2,-2,3,4]
    finally
        FreeIt(a);
    end;
end;

Indexed: function ThreshAbsLT(const Value: Integer; Index: Integer; Len: Integer): TMtxVecInt;

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

#	Name	Type	Description
1	Value	Integer
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.

Examples

var a: TMtxInt;
begin
    CreateIt(a);
    try
        a.SetIt(2,2,[2,-1,3,4]);
        a.ThreshAbsLT(2); // a = [2,-2,3,4]
    finally
        FreeIt(a);
    end;
end;
