Overload List
| # | Signature | Description |
|---|---|---|
| 1 | TVec *SortDescend(); | Sorts vector elements in descending order. |
| 2 | TVec *SortDescend(int Index, int Len); | Sort calling vector elements [Index]..[Index+Len-1]. |
| 3 | TVec *SortDescend(int Index, int Len, TVecInt *IndexVec); | Sort calling vector elements [Index]..[Index+Len-1]. |
| 4 | TVec *SortDescend(TVecInt *IndexVec); | Sort all calling vector elements. IndexVec contains contains the new order of elements. |
Overload 1: TVec *SortDescend();
Sorts vector elements in descending order.
Remarks:
Sort all calling vector elements in descending order.
Note
If the vector is complex, the complex values are first compared by the absolute value and then by the argument.
Examples
#include "Math387.h"
#include "MtxExpr.h"
using namespace Dew;
using namespace Dew::Math;
void Example()
{
Vector a;
a.SetIt(DewArray<double>{ 1.0, 2.0, 3.0, 4.0 });
a.SortDescend();
Vector expected;
expected.SetIt(DewArray<double>{ 4.0, 3.0, 2.0, 1.0 });
if (!a.IsEqual(expected, 1e-10, TCompare::cmpAbsolute))
throw tException("Vector.SortDescend: mismatch");
}#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>{2,1,3,4});
a->SortDescend(); // a = [4,3,2,1]
FreeIt(a);
