pynbody.util.set_array_if_not_same(a_store, a_in, index=None)[source]#

Checks whether a_store and a_in ultimately point to the same buffer; if not, copy a_in into a_store.

Optionally an index or slice can be specified to specify a sub-region of a_store to copy into.

If a_store has units, they are copied from a_in if they are present.

Parameters:

  • a_store (array-like) – The array to copy into

  • a_in (array-like) – The array to copy from

  • index (slice | array-like, optional) – The slice or index within a_store to copy into. If None, the target is the whole array of a_store.
