Inverse Tangent of Four Points on the Unit Circle

```x = [1 0 -1 0];
y = [0 1 0 -1];
d = atan2d(y,x)```
```d =

0    90   180   -90```

D — Angles in degreesscalar value | vector | matrix | N-D array

Angles in degrees, returned as a scalar, vector, matrix, or N-D array. These angles correspond to the points defined by X and Y, and they lie in the closed interval [–180,180].
