Overload List
| # | Signature | Description |
|---|---|---|
| 1 | void SinCos(TMtxVec *SinX, TMtxVec *CosX); | Sine and cosine. |
| 2 | void SinCos(TMtxVec *SinX, TMtxVec *CosX, int SinXIndex, int CosXIndex, int Index, int Len); | Calculates the sine and cosine for calling object elements [Index]..[Index+Len-1]. |
Overload 1: void SinCos(TMtxVec *SinX, TMtxVec *CosX);
Sine and cosine.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | SinX | TMtxVec * | |
| 2 | CosX | TMtxVec * |
Remarks:
Calculates the sine and cosine for all calling object elements and stores the sines to SinX and cosines to CosX. Size and TSparseMtx::Complex property of SinX and CosX are adjusted automatically.
Note
Use this method if you require both sine and cosine.
Examples
#include "Math387.h"
#include "MtxVec.h"
#include "Units.MtxVec.h"
using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxVec;
void Example()
{
TVec *a, *s, *c;
CreateIt(a, s, c);
a->SetIt(false, DewArray<double>{0, PIDIV2, PI});
a->SinCos(s, c); // s=[0,1,0], c =[1,0,-1]
FreeIt(a, s, c);

Overload 2: void SinCos(TMtxVec *SinX, TMtxVec *CosX, int SinXIndex, int CosXIndex, int Index, int Len);
Calculates the sine and cosine for calling object elements [Index]..[Index+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | SinX | TMtxVec * | |
| 2 | CosX | TMtxVec * | |
| 3 | SinXIndex | int | |
| 4 | CosXIndex | int | |
| 5 | Index | int | |
| 6 | Len | int |
Remarks:
stores the sines to SinX elemets [SinXIndex]..[SinXIndex+Len-1] and cosines to CosX elements [CosXIndex]..[CosXIndex+Len-1] elements. Size and TSparseMtx::Complex property of SinX and CosX objects are not set automatically. An exception is raised if TSparseMtx::ConditionCheck and array borders are overrun/underun.
