Quick Start

Using the Stan Math Library

To use the Stan math library include exactly one of the following header files.

include	contents	also includes
stan/math/prim.hpp	primitives	n/a
stan/math/rev.hpp	reverse-mode autodiff	prim.hpp
stan/math/fwd.hpp	forward-mode autodiff	prim.hpp
stan/math/mix.hpp	mixed-mode autodiff	prim.hpp, fwd.hpp, rev.hpp

These top-level header files ensure that all necessary traits files are included in the appropriate order. For more detail, see this Stack Overflow discussion.
