Scope

pressio-ops is a header-only C++ library providing a unified, free-function interface for common linear-algebra operations across multiple backends.

What it offers

• Type traits & MPL: Utilities for detection and metaprogramming that help adapt to different data structures.
• Expressions: Lightweight expression helpers like span, subspan, diagonal, and column for slicing and views.
• Ops (kernels): BLAS-like building blocks—dot, norms, elementwise ops, product (matrix–vector/matrix–matrix), scale, update, fill, set_zero, clone, deep_copy, resize, and more—exposed as free functions (e.g., pressio::ops::product(...)).

Why use it

• One API, many backends: Write operations once and use them with different linear-algebra libraries without refactoring your code.
• Interoperability: Designed to make coupling components less painful.
• Lightweight: Header-only.
