FieldAncillary.
arccosh
(*args, **kwargs)[source]¶ Take the inverse hyperbolic cosine of the data elementwise.
Units are ignored in the calculation. The result has units of radians.
The “standard_name” and “long_name” properties are removed from the result.
New in version 3.2.0.
 Parameters
 Returns
FieldAncillary
orNone
The construct with the inverse hyperbolic cosine of data values. If the operation was inplace then
None
is returned.
Examples:
>>> print(f.array) [[0.5 0.7] [0.9 1.1]] >>> g = f.arccosh() >>> g.Units <Units: radians> >>> print(g.array) [[ nan nan] [ nan 0.44356825]]
>>> print(f.array) [1.2 1.0 0.8 0.6 ] >>> f.arccosh(inplace=True) >>> print(f.array) [0.6223625037147786 0.0 nan nan ] >>> f.mask_invalid(inplace=True) >>> print(f.array) [0.6223625037147786 0.0   ]
