TVec::CumSum Method

TVec Class

Overload List

#SignatureDescription
1TMtxVec *CumSum(int Index, int Len);Cumulative sum.
2TMtxVec *CumSum(TMtxVec *Vec, int VecIndex, int Index, int Len);Calculate the cumulative sum for Vec elements [VecIndex]..[VecIndex+Len-1].
3TVec *CumSum();Cumulative sum.
4TVec *CumSum(TVec *Vec);Calculate the cumulative sum for all Vec elements.

Overload 1: TMtxVec *CumSum(int Index, int Len);

Cumulative sum.

#NameTypeDescription
1Indexint
2Lenint
Remarks:

Calculate the cumulative sum for calling object elements [Index]..[Index+Len-1] in-place. An exception is raised if TVec::ConditionCheck is true and array borders are overrun.

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>{1,2,3,4});
    a->CumSum();  // a = [1,3,6,10]
    FreeIt(a);
}

Overload 2: TMtxVec *CumSum(TMtxVec *Vec, int VecIndex, int Index, int Len);

Calculate the cumulative sum for Vec elements [VecIndex]..[VecIndex+Len-1].

#NameTypeDescription
1VecTMtxVec *
2VecIndexint
3Indexint
4Lenint
Remarks:

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

Overload 3: TVec *CumSum();

Cumulative sum.

Remarks:

Calculate the cumulative sum for all calling object elements in-place.

Examples
#include "MtxVec.h"
#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>{1,2,3,4});
    a->CumSum(); // a = [1,3,6,10]
    FreeIt(a);
}

Overload 4: TVec *CumSum(TVec *Vec);

Calculate the cumulative sum for all Vec elements.

#NameTypeDescription
1VecTVec *
Remarks:

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