Overload 2: TMtxVec *ArcCot(int Index, int Len) const;
Calculate the inverse cotangens of calling object elements [Index]...[Index+Len-1] in-place.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Index | int | |
| 2 | Len | int |
Remarks:
An exception is raised if array borders are overrun.

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::Math387;
using namespace Dew::Math::Units::MtxExpr;
void Example()
{
Vector A, B;
A = {Cplx(1, 0), Cplx(2, 0), Cplx(2, 0), Cplx(4, 1)}; // four complex values
B.ArcCot(A); //or
B = ArcCot(A);

using namespace Dew;
using namespace Dew::Math;
void Example()
{
Vector a;
Vector x;
x.SetIt(DewArray<double>{ 1.0, 1.5, 2.0, 3.0 });
a.ArcCot(x);
Vector expected;
expected.SetIt(DewArray<double>{ 0.785398163397448, 0.588002603547568, 0.463647609000806, 0.321750554396642 });

|---|---|---|---|
| 1 | X | TMtxVec * | |
| 2 | XIndex | int | |
| 3 | Index | int | |
| 4 | Len | int |
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.
