commonDomain(a, b, omit=None)

Common Domain

Parameters

commonDomain(a,b)tests that the domains of variables/arrays a and b are equal,

Returns

the common domain if equal, or None if not equal.

axes not common to the other; the result domain will contain those axes.

If <omit> is specified, as an integer i, skip comparison of the ith dimension and return None for the ith (common) dimension.
