Overload List
| # | Signature | Description |
|---|---|---|
| 1 | TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X); | Inverse tangens of Y/X. |
| 2 | TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X, int YIndex, int XIndex, int Index, int Len); | Calculate the inverse tangens of Y/X. |
Overload 1: TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X);
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 TSparseMtx::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 TSparseMtx::Complex properties do not match.
Note that TSparseMtx::ArcTan is calculated as ArcTan2(1, X).

Overload 2: TMtxVec *ArcTan2(TMtxVec *Y, TMtxVec *X, int YIndex, int XIndex, int Index, int Len);
Calculate the inverse tangens of Y/X.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Y | TMtxVec * | |
| 2 | X | TMtxVec * | |
| 3 | YIndex | int | |
| 4 | XIndex | int | |
| 5 | Index | int | |
| 6 | Len | int |
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.
