See chapter on ODEs in gsl manual. Reduce ur ODE to

y_i`(x)=g_i(x,y_k) for all i, then write functions for evaluating g_i &
delG_i/dely_k (jacobian) (you can put your a_n 's in an array & call them by
reference using pointers in your subroutines), then inititlize the gsl_odeiv
datatypes & use the gsl_odeiv_evolve_apply function to integrate your ODE>
