Recreating our NumPy model in Rust

Now that we can use our NumPy module in Rust, we need to explore how to structure it so that we can use Python modules to solve bigger problems. We will do this by building a NumPy model with a Python interface. To achieve this, we can break down the processes into functions that can be used as and when we need them. The structure of our NumPy model can be seen here:

Figure 7.6 – Rust NumPy model structure  

Considering the flow of our model structure in the preceding diagram, we can build our NumPy model in Rust with the following steps:

1. Build get_weight_matrix and inverse_weight_matrix functions.
2. Build get_parameters, get_times, and get_input_vector functions.
3. Build calculate_parameters and calculate_times functions.
4. Add calculate functions to the Python bindings and add a NumPy dependency to our setup.py file.
5. Build our Python interface.

We can see that each step has dependencies...
