Return an array which reads one member from each source.

Parameters

Parameter	Description
sources	The loadable sources, each of which states the extent of its whole array.
starts	The corner each source is placed at, as an `(n, ndim)` array of sample numbers. By default the sources are laid end to end.
axis	The axis the sources are laid along when `starts` is not given.
shape	The shape of the output; the smallest which holds every member by default.
base_uri	A prefix the sources’ paths are stored relative to. A path which does not start with it is stored whole, and a member’s path is always the two joined.
dtype	The dtype the members are cast to and the array loads as; by default the one they all promote to together. Promotion is not associative, so a caller which must match another order’s result states it.
cast_via	A dtype per source which its samples pass through on the way to the array’s, or None for a member cast straight there. A caller reproducing a buffer which promoted a member at a time states where that buffer rounded each of them.
