A boltzmann code in C to compute the cosmic evolution of interacting dark matter
Daniel Egana-Ugrinovic, 2021.
maincode.c is the core of the code. Physics constants are defined in background.h Derivatives.h defines ODE derivatives as macros integrals.h are functions for Euler integration RKF.h contains the ODE for the cosmic perturbations structures.h defines the perturbations to be solved in structures thermodynamics.h defines basic thermodynamics functions, such as sound speed
