Cython example of exposing C-computed arrays in Python without data copies

This technical article provides a detailed Cython example for efficiently exposing C-computed arrays to Python without data copies. It explains how to use PyArray_SimpleNewFromData from NumPy's C API, includes a wrapper class for memory management, and demonstrates a complete binding to a C function. The focus is on performance and maintainability for integrating C and Python in scientific computing or systems programming.
