'inv' function generality

[awson]

Crocodile's 'inv' function is described as "Invert a hermitian-symetric two-dimensional grid. The hermitian symetric dimension is the second (last) index, like in numpy.fft":

crocodile/synthesis.py

Line 211 in 8d5132f

"""Invert a hermitian-symetric two-dimensional grid.

.

AFAIUI, this is related to how the sample uv data are generated, see

crocodile/synthesis.py

Line 356 in 8d5132f

v=numpy.hstack([v, numpy.conj(v)])

.

The question is: what if we use uv data generated by Oskar? Do they have the same structure (hermitean-symmetric)? And if they have more general structure then how should 'inv' look like in this general case?
