cf.Field.equivalent

Field.equivalent(other, rtol=None, atol=None, traceback=False)

True if two fields are equivalent, False otherwise

two fields are equivalent if:

• They have the same identity, as defined by their identity methods.
• The same rank, as given by their rank attributes.
• Their data arrays are the same after accounting for different but equivalent:
  • Units
  • Number of size one dimensions (if squeeze is True),
  • Dimension directions (if use_directions is True)
  • Dimension orders (if transpose is set to a dictionary).
• Both fields’ domains must have the same rankdimensionality and where a dimension in one field has an identity inferred a 1-d coordinate, the other field has a matching dimension whose identity inferred is inferred from a 1-d coordinate with an equivalent data array.
  • The rank, as given by their `~cf.Field.rank

Examples 1:

>>> b = f.equivalent(g)

Parameters:

other : object

atol : float, optional

The absolute tolerance for all numerical comparisons, By default the value returned by the cf.ATOL function is used.

rtol : float, optional

The relative tolerance for all numerical comparisons, By default the value returned by the cf.RTOL function is used.

traceback : bool, optional

If True then print a traceback highlighting where the two fields differ.

Returns:

out : bool

Whether or not the two fields are equivalent.
