minimax_exp_gw Module Reference

Routines to calculate the minimax coefficients in order to approximate 1/x as a sum over exponential functions 1/x ~ SUM_{i}^{K} w_i EXP(-a_i * x) for x belonging to [1:Rc]. This module contains coefficients for minimax approximations with 26, 28, 30, 32, 34 points that give well-converged GW results. More...
