xray.ufuncs.cosh¶
- xray.ufuncs.cosh(*args, **kwargs)¶
xray specific variant of numpy.cosh. Handles xray.Dataset, xray.DataArray, xray.Variable, numpy.ndarray and dask.array.Array objects with automatic dispatching.
Documentation from numpy:
cosh(x[, out])
Hyperbolic cosine, element-wise.
Equivalent to 1/2 * (np.exp(x) + np.exp(-x)) and np.cos(1j*x).
Parameters: x : array_like
Input array.
Returns: out : ndarray
Output array of same shape as x.
Examples
>>> np.cosh(0) 1.0
The hyperbolic cosine describes the shape of a hanging cable:
>>> import matplotlib.pyplot as plt >>> x = np.linspace(-4, 4, 1000) >>> plt.plot(x, np.cosh(x)) >>> plt.show()
