One minor correction though, because I found that it fails to infer the period if none is given. The divide should be a multiplication I believe, i.e. ```python import xarray import numpy as np def add_cyclic_point(xarray_obj, dim, period=None): if period is None: period = xarray_obj.sizes[dim] * xarray_obj.coords[dim][:2].diff(dim).item() first_point = xarray_obj.isel({dim: slice(1)}) first_point.coords[dim] = first_point.coords[dim]+period return xarray.concat([xarray_obj, first_point], dim=dim) ``` |
