This is the API documentation for Eigen3. You can download it as a tgz archive for offline reading.

Eigen2 users: here is a Porting from Eigen2 to Eigen3 guide to help porting your application.

For a first contact with Eigen, the best place is to have a look at the tutorial. The short reference page gives you a quite complete description of the API in a very condensed format that is specially useful to recall the syntax of a particular feature, or to have a quick look at the API. For Matlab users, there is also a ASCII quick reference with Matlab translations. The Modules and Classes tabs at the top of this page give you access to the API documentation of individual classes and functions.
