arctan

mxnet.ndarray.sparse.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
