In 2005, Travis Oliphant was an information scientist working on medical and biological imaging at Brigham Young University in Provo, Utah, when he began work on NumPy, a library that has become a ...

There is a phenomenon in the Python programming language that affects the efficiency of data representation and memory. I call it the "invisible line." This invisible line might seem innocuous at ...

The following code using @cython.ufunc, a slight variation of the documentation, crashes reproducibly on import on Windows with Python 3.11/3.12, Cython 3.0.9/3.1.0a0, numpy 1.26.4, Visual Studio 2022 ...

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...

Abstract: Almost all humankind depends on satellite technology orbiting the Earth. However, space operations are increasingly endangered by the rapidly growing number of orbiting objects and debris.

We're attempting to upgrade to Cython 3.0.x in pandas-dev/pandas#55179, but seeing some performance regressions. We've tracked a number of these down to our use of ndarray without any dtype or ...

Long in development, the new major release of the Python-to-C compiler sheds legacy Python support and readies Cython developers for big changes in Python. The main goal behind Cython is to make it ...

Abstract: This paper proposes a library for implementing the genetic algorithm using Python mainly in NumPy and speeding-up its execution using Cython. The preliminary Python implementation is ...
