TVec::Log10 Method

Overload List

#SignatureDescription
1TMtxVec *Log10();Log base 10.
2TMtxVec *Log10(TMtxVec *X);Calculate the log base 10 for all X elements.
3TMtxVec *Log10(int Index, int Len);Calculate the log base 10 for calling object elements [Index]..[Index+Len-1] in-place.
4TMtxVec *Log10(TMtxVec *X, int XIndex, int Index, int Len);Calculate the log base 10 for X elements [XIndex]..[XIndex+Len-1].

Overload 1: TMtxVec *Log10();

Log base 10.

Remarks:

Calculate the log base 10 for all calling object elements in-place.

Examples
#include "Units.MtxVec.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxVec;

void Example()
{
    TVec* a;
    CreateIt(a);
    a->SetIt(false, DewArray<double>{10,100,1000,10000});
    a->Log10(); // a = [1,2,3,4]
    FreeIt(a);
}
#include "Math387.h"
#include "MtxExpr.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Vector a;
    a.SetIt(DewArray<double>{ 1.0, 2.0, 4.0, 10.0 });
    a.Log10();
    Vector expected;
    expected.SetIt(DewArray<double>{ 0.0, 0.301029995663981, 0.602059991327962, 1.0 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.Log10: mismatch");
}

Overload 2: TMtxVec *Log10(TMtxVec *X);

Calculate the log base 10 for all X elements.

#NameTypeDescription
1XTMtxVec *
Remarks:

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

Examples
#include "Math387.h"
#include "MtxExpr.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Vector a;
    Vector x;
    x.SetIt(DewArray<double>{ 1.0, 2.0, 4.0, 10.0 });
    a.Log10(x);
    Vector expected;
    expected.SetIt(DewArray<double>{ 0.0, 0.301029995663981, 0.602059991327962, 1.0 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.Log10: mismatch");

Overload 3: TMtxVec *Log10(int Index, int Len);

Calculate the log base 10 for calling object elements [Index]..[Index+Len-1] in-place.

#NameTypeDescription
1Indexint
2Lenint
Remarks:

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

Overload 4: TMtxVec *Log10(TMtxVec *X, int XIndex, int Index, int Len);

Calculate the log base 10 for X elements [XIndex]..[XIndex+Len-1].

#NameTypeDescription
1XTMtxVec *
2XIndexint
3Indexint
4Lenint
Remarks:

Store the results in the calling object elements [Index]..[Index+Len-1]. Size and TVec::Complex properties of the calling object must be set explicitly. An exception is raised if TVec::ConditionCheck is True and array borders are overrun.
