TSparseMtx Class

Overload List

#SignatureDescription
1TMtxVec *ArcCsch();Inverse hyperbolic cosecant.
2TMtxVec *ArcCsch(int Index, int Len);Calculate the inverse hyperbolic cosecant for calling object elements [Index]...[Index+Len-1] in-place.
3TMtxVec *ArcCsch(TMtxVec *X);Calculate the inverse hyperbolic cosecant for all X object elements.
4TMtxVec *ArcCsch(TMtxVec *X, int XIndex, int Index, int Len);Calculate the inverse hyperbolic cosecant for X object elements [XIndex]..[XIndex+Len-1].

Overload 1: TMtxVec *ArcCsch();

Inverse hyperbolic cosecant.

Remarks:

Calculate the inverse hyperbolic cosecant for all caling object elements in-place.

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

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Vector a;
    a.SetIt(DewArray<double>{ 0.5, 1.0, 2.0, 3.0 });
    a.ArcCsch();
    Vector expected;
    expected.SetIt(DewArray<double>{ 1.44363547517881, 0.881373587019543, 0.481211825059603, 0.327450150237258 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.ArcCsch: mismatch");
}

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

Calculate the inverse hyperbolic cosecant for all X object elements.

#NameTypeDescription
1XTMtxVec *
Remarks:

Store the results in calling object. Size and TSparseMtx::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>{ 0.5, 1.0, 2.0, 3.0 });
    a.ArcCsch(x);
    Vector expected;
    expected.SetIt(DewArray<double>{ 1.44363547517881, 0.881373587019543, 0.481211825059603, 0.327450150237258 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.ArcCsch: mismatch");

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

Calculate the inverse hyperbolic cosecant for X object elements [XIndex]..[XIndex+Len-1].

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

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