Description
============


CAMB is a cosmology code for calculating cosmological observables, including
CMB, lensing, source count and 21cm angular power spectra, matter power spectra, transfer functions
and background evolution. The code is in Python, with numerical code implemented in fast modern Fortran.

See the `CAMB python example notebook <https://camb.readthedocs.org/en/latest/CAMBdemo.html>`_ for a
quick introduction to how to use the CAMB Python package.

To install the CAMB python package on your computer run::

    pip install camb [--user]

The --user is optional and only required if you don't have write permission to your main python installation.
You will need gfortran 6 or higher installed to compile. Binary files for Windows are also provided, so these are used instead if no
gfortran installation is found on Windows machines.

The python wrapper provides a module called "camb" documented in the `Python CAMB documentation <https://camb.readthedocs.io/en/latest/>`_.
