Installation

You can get the celerite source code by running

git clone https://github.com/dfm/celerite.git

celerite is a header-only library and the header files can be found in the cpp/include directory in the source tree.

Dependencies

The only hard dependency is a recent version of Eigen. celerite has been tested with Eigen 3.2.9 but somewhat older versions should also work.

Testing

The unit tests can be run using CMake. Navigate to the cpp directory and execute:

cmake .
make
make test

LAPACK Support

If you compile with the -DWITH_LAPACK macro and link to an appropriate BLAS/LAPACK implementation, celerite will be able to use LAPACK to solve the extended band system. This can yield performance gains for “wide” problems. To compile the examples with this support, run:

cmake . -DLAPACK=ON
