Inverse hyperbolic cosine, element-wise.
LAX-backend implementation of
Original docstring below.
x (array_like) – Input array.
out (ndarray, None, or tuple of ndarray and None, optional) – A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
arccosh – Array of the same shape as x. This is a scalar if x is a scalar.
