Introduction

matten is a developer-experience-first multidimensional array (tensor) library for Rust — the family car for small numerical and data-exploration proof-of-concept work.

Maturity labels in this book — such as production-ready — describe stability within that scope, not performance or scale. matten optimizes for time to a runnable PoC, not benchmark leadership.

This book is organized by reader:

• New users — philosophy and a quick start.
• Reference — the rules that shape the public API.
• Contributors — project layout, milestones, and process.

This documentation tracks the current 0.28 family, which moves the matten-ndarray bridge to ndarray 0.17 (RFC-062), on top of the completed companion-maturity line: matten-ndarray is production-ready and matten-mlprep and matten-data are production-ready candidates.
