cosh
(*args, **kwargs)[source]¶ Take the hyperbolic cosine of the data elementwise.
Units are accounted for in the calculation. If the units are not equivalent to radians (such as Kelvin) then they are treated as if they were radians. For example, the the hyperbolic cosine of 0 degrees_east is 1.0, as is the hyperbolic cosine of 1.57079632 radians.
The output units are changed to ‘1’ (nondimensional).
The “standard_name” and “long_name” properties are removed from the result.
New in version 3.1.0.
 Parameters
 Returns
FieldAncillary
orNone
The construct with the hyperbolic cosine of data values. If the operation was inplace then
None
is returned.
Examples:
>>> f.Units <Units: degrees_north> >>> print(f.array) [[90 0 90 ]] >>> g = f.cosh() >>> g.Units <Units: 1> >>> print(g.array) [[2.5091784786580567 1.0 2.5091784786580567 ]]
>>> f.Units <Units: m s1> >>> print(f.array) [[1 2 3 ]] >>> f.cosh(inplace=True) >>> f.Units <Units: 1> >>> print(f.array) [[1.5430806348152437 3.7621956910836314 10.067661995777765 ]]
