### Overview of package minimax

parameters for minimax approximations of 1/x

- minimax_exp
- 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].
- minimax_exp_k15
- 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 1 <= k <= 15.
- minimax_exp_k53
- 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 1 <= k <= 53. Generated from data from http://www.mis.mpg.de/scicomp/EXP_SUM/1_x This module should not be modified manually and should not be used anywhere except in main minimax module. This file was created using the scripts in cp2k/tools/minimax_tools.
- 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].
