   - get_S: obtain the overlap matrix formed by localized orbitals (for LCAO basis with multiple k points). the file name is `SR.csr` with file format being the same as that generated by [out_mat_hs2](#out_mat_hs2)
   - gen_bessel: generates projectors, i.e., a series of Bessel functions, for the DeePKS method (for LCAO basis only); see also keywords `bessel_descriptor_lmax`, `bessel_descriptor_rcut` and `bessel_descriptor_tolerence`. A file named `jle.orb` will be generated which contains the projectors. An example is provided in examples/H2O-deepks-pw
