Compute the inverse tangent of the argument. The function is applied element-wise and the result has always the same type as the argument x. The values of the result are in the range -pi .. pi.
- Usage 1
atan(x)- x
- a scalar, vector or matrix
- Result
- The inverse tangent of x.
- Usage 2
atan(y, x)- Result
- The inverse tangent of y / x. This function can be used to compute the phase
