#include "config-f90.h"

Data Types
interface	ELPA1::get_elpa_row_col_comms
	get_elpa_row_col_comms: old, deprecated Fortran function to create the MPI communicators for ELPA. Better use "elpa_get_communicators" The interface and variable definition is the same as in "elpa_get_communicators" More...
interface	ELPA1::solve_evp_real
	solve_evp_real: old, deprecated Fortran function to solve the real eigenvalue problem with 1-stage solver. Better use "solve_evp_real_1stage" More...
interface	ELPA1::solve_evp_complex
	solve_evp_complex: old, deprecated Fortran function to solve the complex eigenvalue problem with 1-stage solver. Better use "solve_evp_complex_1stage" More...

Modules
module	ELPA1
	Fortran module which provides the routines to use the one-stage ELPA solver.
