Operations on Vectors
=====================

This example shows how to perform some basic operations slicing and selecting vectors.
This is designed to be very flexible and powerful.  Many operations such as slicing with a
boolean array are supported.

Additionally, lazy operations are supported and can be chained together. These are often faster
than their non-lazy counterparts as ``dask`` very effectively prunes the computation graph.
