strata¶

A modern, lazy C++26 tensor expression engine.

Warning

strata is young and its API still changes from one pull request to the next.

Where to start¶

Getting started: requirements, adding strata to a CMake project, building.
Examples: every program in examples/, from first steps to einsum.
Tensors and views and Expressions: the two ideas the rest is built on.
einsum: contractions, with their formulas, and what they cost.
The cost model: when a part of an expression is computed into a buffer first, and why.
Shapes and extents: how a tensor's size is written in its type, and what is checked when.
The API reference, generated from the doc comments.
