TVec::Cbrt Method

Overload List

#SignatureDescription
1TMtxVec *Cbrt();The cube root.
2TMtxVec *Cbrt(int Index, int Len);Calculate the cube root of calling object elements [Index]..[Index+Len-1] in-place.
3TMtxVec *Cbrt(TMtxVec *X);Calculate the cube root of all X object elements.
4TMtxVec *Cbrt(TMtxVec *X, int XIndex, int Index, int Len);Calculate the cube root of X object elements [XIndex]..[XIndex+Len-1].

Overload 1: TMtxVec *Cbrt();

The cube root.

Remarks:

Calculate the cube root of 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(true, DewArray<double>{1,8});
    a->Cbrt(); // a = [1,2]
    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, 8.0, 27.0, 64.0 });
    a.Cbrt();
    Vector expected;
    expected.SetIt(DewArray<double>{ 1.0, 2.0, 3.0, 4.0 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.Cbrt: mismatch");

Overload 3: TMtxVec *Cbrt(TMtxVec *X);

Calculate the cube root of all X object elements.

#NameTypeDescription
1XTMtxVec *
Remarks:

Store the results in calling object. Size and TVec::Complex properties of calling object are adjusted automatically.

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, 8.0, 27.0, 64.0 });
    a.Cbrt(x);
    Vector expected;
    expected.SetIt(DewArray<double>{ 1.0, 2.0, 3.0, 4.0 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.Cbrt: mismatch");

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

Calculate the cube root of X object elements [XIndex]..[XIndex+Len-1].

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

The results are stored 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 array borders are overrun.
