** Electron-electron rescaled distances ** Electron-electron rescaled distances
~ee_distance_rescaled~ stores the matrix of the rescaled distances between all
pairs of electrons:
\[
C_{ij} = \left( 1 - \exp{-\kappa C_{ij}}\right)/\kappa
\]
where \(C_{ij}\) is the matrix of electron-electron distances.
