Overload List
| # | Signature | Description |
|---|---|---|
| 1 | TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X) const; | Inverse tangens of Y/X. |
| 2 | TMtxVec *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] and store the results in calling object elements [Index]..[Index+Len-1]. |
Overload 1: TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X) const;
Inverse tangens of Y/X.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Y | TMtxVec * | |
| 2 | X | TMtxVec * |
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 Matrix::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 Matrix::Complex properties do not match.
The result will fall in the range from -PI to PI radians.
Note
Matrix::ArcTan is calculated as ArcTan2(1, X).
