mxnet.np.cosh¶
-
cosh
(x, out=None, **kwargs)¶ Hyperbolic cosine, element-wise. Equivalent to
1/2 * (np.exp(x) + np.exp(-x))
andnp.cos(1j*x)
.- Parameters
x (ndarray or scalar) – Input array or scalar.
out (ndarray or None) – 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. The dtype of the output is the same as that of the input if the input is an ndarray.
- Returns
y – The corresponding hyperbolic cosine values. This is a scalar if x is a scalar.
- Return type
ndarray or scalar
Notes
This function only supports input type of float.
Examples
>>> np.cosh(0) 1.0
