mxnet.ndarray.arccos¶
-
mxnet.ndarray.arccos(data=None, out=None, name=None, **kwargs)¶ Returns element-wise inverse cosine of the input array.
The input should be in range [-1, 1]. The output is in the closed interval \([0, \pi]\)
\[arccos([-1, -.707, 0, .707, 1]) = [\pi, 3\pi/4, \pi/2, \pi/4, 0]\]The storage type of
