TSparseMtx.Exp10 Method

Overload List

#	Signature	Description
1	function Exp10: TMtxVec;	Exponent base 10 (10^).
	└ indexed: function Exp10(Index: Integer; Len: Integer): TMtxVec;
2	function Exp10(const X: TMtxVec): TMtxVec;	Calculate the exponent base 10 (10^) for all X elements.
	└ indexed: function Exp10(const X: TMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TMtxVec;

Overload 1: function Exp10: TMtxVec;

Exponent base 10 (10^).

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

Remarks:

Calculate the exponent base 10 (10^) for all calling object elements in-place.

Examples

var a,b: Matrix;
begin
    a.SetIt(2,2,False,[1,2,3,4]);  // a = [1,2,3,4]
    a.Exp10;        // a = [10,100,1000,10000]
    a := Exp10(a);
    b.Exp10(a);  //same as
    b := Exp10(a);
end;

var
    a, expected: Matrix;
begin
    a := [[0.0, 1.0], [2.0, 3.0]];
    a.Exp10;
    expected := [[1.0, 10.0], [100.0, 1000.0]];
    if not a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute) then
        raise Exception.Create('Matrix.Exp10: mismatch');
end;

Indexed: function Exp10(Index: Integer; Len: Integer): TMtxVec;

Calculate the exponent base 10 (10^) for calling object elements [Index]..[Index+Len-1] in-place.

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

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

Remarks:

An exception is raised if TMtxVecBase.ConditionCheck is True and array borders are overrun.

Overload 2: function Exp10(const X: TMtxVec): TMtxVec;

Calculate the exponent base 10 (10^) for all X elements.

#	Name	Type	Description
1	X	TMtxVec	source TVec or TMtx

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

Remarks:

Store the results in the calling object. Size and TMtxVec.Complex properties of the calling vector are set implicitly to match the X object.

Examples

var
    a, x, expected: Matrix;
begin
    x := [[0.0, 1.0], [2.0, 3.0]];
    a.Exp10(x);
    expected := [[1.0, 10.0], [100.0, 1000.0]];
    if not a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute) then
        raise Exception.Create('Matrix.Exp10: mismatch');
end;

Indexed: function Exp10(const X: TMtxVec; XIndex: Integer; Index: Integer; Len: Integer): TMtxVec;

Calculate the exponent base 10 (10^) for X elements [XIndex]..[XIndex+Len-1].

#	Name	Type	Description
1	X	TMtxVec	source TVec or TMtx
2	XIndex	Integer	X start index
3	Index	Integer	start index
4	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.
