- For
- Python developers with interpreter-bound numeric loops
- Worth noticing
- NumPy arrays and views pass by pointer with shape and strides rather than being copied.
Field notes
A function's first call supplies the argument types used to generate and compile specialized C; later calls with matching types use the cached result. The examples include an exponential moving average and edit distance, while the page also describes passing NumPy views without copying and allocating arrays inside compiled code.
