numerical_multiedge_match(attr, default, rtol=1e-05, atol=1e-08)

Returns a comparison function for a numerical edge attribute.

The value(s) of the attr(s) must be numerical and sortable. If the sorted list of values from G1 and G2 are the same within some tolerance, then the constructed function returns True.

Parameters :

attr : string | list

The numerical edge attribute to compare, or a list of numerical edge attributes to compare.

default : value | list

The default value for the numerical edge attribute, or a list of default values for the numerical edge attributes.

rtol : float

The relative error tolerance.

atol : float

The absolute error tolerance.

Returns :

match : function

The customized, numerical
