mxnet.ndarray.sparse.arcsin¶

mxnet.ndarray.sparse.arcsin(data=None, out=None, name=None, **kwargs)¶

Returns element-wise inverse sine of the input array.

The input should be in the range [-1, 1]. The output is in the closed interval of [\(-\pi/2\), \(\pi/2\)].

\[arcsin([-1, -.707, 0, .707, 1]) = [-\pi/2, -\pi/4, 0, \pi/4, \pi/2]\]

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

arcsin(default) = default

arcsin(row_sparse) = row_sparse

arcsin(csr) = csr

Defined in src/operator/tensor/elemwise_unary_op_trig.cc:L104

Parameters

Returns

out – The output of this function.

Return type

NDArray or list of NDArrays
