Effectively yes. When you return an object, the id (i.e. memory address) of the object inside the function is the same as the id of the object outside the function. It doesn't make a copy or anything.

Here's one way to do that, using the attributes **data**, **indices**, **indptr** - `m` is the *csr\_matrix*:
