clMatrix::ArcTan2 Method

Overload List

#SignatureDescription
1TOpenCLMtxVec *ArcTan2(TOpenCLMtxVec *Y, TOpenCLMtxVec *X) const;Inverse tangens of Y/X.
2TOpenCLMtxVec *ArcTan2(TOpenCLMtxVec *Y, TOpenCLMtxVec *X, int YIndex, int XIndex, int Index, int Len) const;Calculate the inverse tangens of Y/X.

Overload 1: TOpenCLMtxVec *ArcTan2(TOpenCLMtxVec *Y, TOpenCLMtxVec *X) const;

Inverse tangens of Y/X.

#NameTypeDescription
1YTOpenCLMtxVec *
2XTOpenCLMtxVec *
Remarks:

Calculates the inverse tangens of Y/X, and returns an angle in the correct quadrant. The results are stored in calling object elements. Size and clMatrix::Complex properties of calling object are adjusted automatically to match those of X and Y objects. An exception is raised if X and Y size and clMatrix::Complex properties do not match.

Note that clMatrix::ArcTan is calculated as ArcTan2(1, X).

Overload 2: TOpenCLMtxVec *ArcTan2(TOpenCLMtxVec *Y, TOpenCLMtxVec *X, int YIndex, int XIndex, int Index, int Len) const;

Calculate the inverse tangens of Y/X.

#NameTypeDescription

3YIndexint
4XIndexint
5Indexint
6Lenint
Remarks:

Calculation uses Y elements [YIndex]..[YIndex+Len-1], X elements [XIndex]..[XIndex+Len-1] and stores the results in calling object elements [Index]..[Index+Len-1]. An exception is raised if array borders are overrun.
