module | minimax_rpa |
| Routines to calculate the minimax coefficients for approximating 1/x as 1/x ~ 1/pi SUM_{i}^{K} w_i x^2/(x^2+a_i^2)^2 for x belonging to [1:Rc].

subroutine, public | minimax_rpa::get_rpa_minimax_coeff (k, e_range, aw, ierr, print_warning) |
| The a_i and w_i coefficient are stored in aw such that the first 1:K elements correspond to a_i and the K+1:2k correspond to w_i. All a_i and w_i have been fitted with a 12th order polynomial as a function of Rc for each value of K.
