Overload 1: TMtxVec *Cbrt() const;
The cube root.
Remarks:
Calculate the cube root of all calling object elements in-place.
Examples
#include "Math387.h"
#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Matrix a;
a.SetIt(2, 2, false, DewArray<double>{ 1.0, 8.0, 27.0, 64.0 });
a.Cbrt();
Matrix expected;
expected.SetIt(2, 2, false, DewArray<double>{ 1.0, 2.0, 3.0, 4.0 });
if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))

}#include "MtxExpr.h"
#include "Units.MtxExpr.h"
using namespace Dew;

void Example()
{
Matrix v, w;
v.SetIt(1, 2, false, DewArray<double>{1, 8});
v.Cbrt(); // v = [1,2], same as:
v = Cbrt(v);
w = Cbrt(v); //same as:
w.Cbrt(v);

| # | Name | Type | Description |
|---|---|---|---|
| 1 | Index | int | |
| 2 | Len | int |
Remarks:
An exception is raised if array borders are overrun.
Examples
#include "MtxExpr.h"
#include "Units.MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxExpr;
void Example()
{
Matrix v, w;
v = {{1, 8}};
v.Cbrt(); // v = [1,2], same as:
v = Cbrt(v);
w = Cbrt(v); //same as:
w.Cbrt(v);

Overload 3: TMtxVec *Cbrt(TMtxVec *X) const;
Calculate the cube root of all X object elements and store the results in calling object.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TMtxVec * |
Remarks:
Size and Matrix::Complex properties of calling object are adjusted automatically.
Examples
#include "Math387.h"
#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Matrix a;
Matrix x;
x.SetIt(2, 2, false, DewArray<double>{ 1.0, 8.0, 27.0, 64.0 });
a.Cbrt(x);
Matrix expected;
expected.SetIt(2, 2, false, DewArray<double>{ 1.0, 2.0, 3.0, 4.0 });
if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
throw tException("Matrix.Cbrt: mismatch");

Overload 4: TMtxVec *Cbrt(TMtxVec *X, int XIndex, int Index, int Len) const;
Calculate the cube root of X object elements [XIndex]..[XIndex+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TMtxVec * | |
| 2 | XIndex | int | |
| 3 | Index | int | |
| 4 | Len | int |
Remarks:
The results are stored in the calling object elements [Index]..[Index+Len-1]. Size and Matrix::Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
