Mathematical data science through complete, executable experiments by Gabriel Peyré and contributors.

Start with the Python notebooks, or browse numerical-tours.com. The main collection covers imaging, optimization, optimal transport, machine learning, signals, and geometry. All worked examples show their implementations directly in the notebooks.

The matlab, julia, and r folders contain the original language editions. The website source lives on the gh-pages branch; Python content lives on master.

For installation, execution checks, and website export, see the maintenance guide.
