clMatrix::SinCos Method

Overload List

#SignatureDescription
1void SinCos(TOpenCLMtxVec *SinX, TOpenCLMtxVec *CosX) const;Sine and cosine.
2void SinCos(TOpenCLMtxVec *SinX, TOpenCLMtxVec *CosX, int SinXIndex, int CosXIndex, int Index, int Len) const;Calculates the sine and cosine for calling object elements [Index]..[Index+Len-1].

Overload 1: void SinCos(TOpenCLMtxVec *SinX, TOpenCLMtxVec *CosX) const;

Sine and cosine.

#NameTypeDescription
1SinXTOpenCLMtxVec *
2CosXTOpenCLMtxVec *
Remarks:

Calculates the sine and cosine for all calling object elements and stores the sines to SinX and cosines to CosX. Size and clMatrix::Complex property of SinX and CosX are adjusted automatically.

Note
Use this method if you require both sine and cosine.

Examples
#include "clMtxExpr.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    clMatrix a;
    clMatrix s, c;

    a.CopyFromArray(2, 2, DewArray<float>{0, PIDIV2, PI, 0});
    a.SinCos(s, c); // s=[0,1,0,0], c =[1,0,-1,1]
}

Overload 2: void SinCos(TOpenCLMtxVec *SinX, TOpenCLMtxVec *CosX, int SinXIndex, int CosXIndex, int Index, int Len) const;

Calculates the sine and cosine for calling object elements [Index]..[Index+Len-1].

Remarks:

stores the sines to SinX elemets [SinXIndex]..[SinXIndex+Len-1] and cosines to CosX elements [CosXIndex]..[CosXIndex+Len-1] elements. Size and clMatrix::Complex property of SinX and CosX objects are not set automatically. An exception is raised if array borders are overrun/underun.
