atan2(y, x) |
| See Also | tan , atan , angle |
y / x where
y and x are real or double-precision matrices.
If the types of x and y do not agree,
coercion
is done and then the result is computed.
The elements of the result are between -pi and +pi.
atan2(1., 1.)
returns
0.785398
Even though x is in the denominator in the definition above,
zero is a valid value for an element of x.
atan2([0, 1., 0, -1.], [-1., 0, 1., 0])
returns
[ 3.14159 , 1.5708 , 0 , -1.5708 ]
