TVecInt.Abs Method

Overload List

#	Signature	Description
1	function Abs: TMtxVecInt;	Absolute values.
	└ indexed: function Abs(Index: Integer; Len: Integer): TMtxVecInt;
2	function Abs(const Src: TMtxVecInt): TMtxVecInt;	Absolute values of all Src vector elements.
	└ indexed: function Abs(const Src: TMtxVecInt; SrcIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Overload 1: function Abs: TMtxVecInt;

Absolute values.

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

Remarks:

Calculate the absolute value of all calling object elements in-place.

Examples

Uses MtxVecInt;

procedure Example;
var a: TVecInt;
c: double;
begin
    CreateIt(a);
    a.SetIt([1,-2,3,4]);
    a.Abs; // a = [1,2,3,4]
    FreeIt(a);
end;

Indexed: function Abs(Index: Integer; Len: Integer): TMtxVecInt;

Absolute values of calling object elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	Index	Integer	start index
2	Len	Integer	element count

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

Returns: calling vector elements [Index]..[Index+Len-1] ansolute vslues.

Remarks:

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

Note
Please note the calling vector elements [Index]..[Index+Len-1] are overwritten with result of routine call.

Examples

Uses MtxVecInt;

procedure Example;
var a: TMtxInt;
c: double;
begin
    CreateIt(a);
    a.SetIt([1,-2,3,4]);
    a.Abs; // a = [1,2,3,4]
    FreeIt(a);
end;

Overload 2: function Abs(const Src: TMtxVecInt): TMtxVecInt;

Absolute values of all Src vector elements.

#	Name	Type	Description
1	Src	TMtxVecInt	source TVecInt or TMtxInt

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

Returns: Src vector elements ansolute vslues.

Indexed: function Abs(const Src: TMtxVecInt; SrcIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Absolute values of Src vector elements [VecIndex]..[VecIndex+Len-1].

#	Name	Type	Description
1	Src	TMtxVecInt	source TVecInt or TMtxInt
2	SrcIndex	Integer	source start index
3	Index	Integer	start index
4	Len	Integer	element count

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

Returns: Src vector elements [VecIndex]..[VecIndex+Len-1] absolute values in calling vector elements [Index]..[Index+Len-1].

Remarks:

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

Note
Please note the calling vector elements [Index]..[Index+Len-1] are overwritten with result of routine call.
