mxnet.ndarray.arctan

mxnet.ndarray.arctan(data=None, out=None, name=None, **kwargs)

Returns element-wise inverse tangent of the input array.

The output is in the closed interval \([-\pi/2, \pi/2]\)

\[arctan([-1, 0, 1]) = [-\pi/4, 0, \pi/4]\]

The storage type of arctan output depends upon the input storage type:

• arctan(default) = default

• arctan(row_sparse) = row_sparse

• arctan(csr) = csr

Defined in src/operator/tensor/elemwise_unary_op_trig.cc:L144

Parameters

• data (NDArray) – The input array.

• out (NDArray, optional) – The output NDArray to hold the result.

Returns

out – The output of this function.

Return type

NDArray or list of NDArrays
