Vector::ArcTan2 Method

Overload List

#SignatureDescription
1TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X) const;Inverse tangens of Y/X.
2TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X, int YIndex, int XIndex, int Index, int Len) const;Calculate the inverse tangens of Y/X by using Y elements [YIndex]..[YIndex+Len-1], X elements [XIndex]..[XIndex+Len-1].

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

Inverse tangens of Y/X.

#NameTypeDescription
1YTMtxVec *
2XTMtxVec *
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 Vector::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 Vector::Complex properties do not match.

The result will fall in the range from -PI to PI radians. Note that Vector::ArcTan is calculated as ArcTan2(1, X).
