Overload List

#SignatureDescription
1TMtxVec *Sec() const;Secant.
2TMtxVec *Sec(int Index, int Len) const;Calculate the secant of calling object elements [Index]...[Index+Len-1] in-place.
3TMtxVec *Sec(TMtxVec *X) const;Calculate the secant of all X object elements.
4TMtxVec *Sec(TMtxVec *X, int XIndex, int Index, int Len) const;Calculate the secant of X object elements [XIndex]...[XIndex+Len-1].

Overload 1: TMtxVec *Sec() const;

Secant.

Remarks:

Calculate the secant of 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>{ 0.0, 0.523598775598299, 0.785398163397448, 1.0471975511966 });
    a.Sec();
    Vector expected;
    expected.SetIt(DewArray<double>{ 1.0, 1.15470053837925, 1.41421356237309, 2.0 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.Sec: mismatch");
}
#include "MtxExpr.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Vector a;

    a.SetIt(true, DewArray<double>{1, -2, 3, 4});
    a.Sec(); // Computes complex secant
}

Overload 2: TMtxVec *Sec(int Index, int Len) const;

Calculate the secant of calling object elements [Index]...[Index+Len-1] in-place.

#NameTypeDescription
1Indexint
2Lenint
Remarks:

An exception is raised if array borders are overrun.

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

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::Math387;

void Example()
{
    Vector a;

    a = {Cplx(1, -2), Cplx(3, 4)};
    a.Sec(); // Computes complex secant
}

Overload 3: TMtxVec *Sec(TMtxVec *X) const;

Calculate the secant of all X object elements.

#NameTypeDescription
1XTMtxVec *
Remarks:

Store the results in the calling object. Size and Vector::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>{ 0.0, 0.523598775598299, 0.785398163397448, 1.0471975511966 });
    a.Sec(x);
    Vector expected;
    expected.SetIt(DewArray<double>{ 1.0, 1.15470053837925, 1.41421356237309, 2.0 });
    if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
        throw tException("Vector.Sec: mismatch");

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

Calculate the secant of 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 Vector::Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
