Creating a Shared Memory backed Fixed-Size Matrix/Vector

Hello, I'm trying to use nalgebra along with a [shared memory crate](https://crates.io/crates/shared_memory) to communicate with a separate Python process (so it could be read by Numpy). I was wondering whether there would be a way to create a matrix or vector of a fixed size in shared memory to avoid data copy. If so would anyone be able to provide me with some advice on how to go about this for nalgebra?
Thanks in advance 😁, any help or advice would be greatly appreciated
