#%% The aim of this test is to verify that different values
#%% of input variable 'ortalg' give the same results for
#%% total energy. 'ortalg' is use in the conjugate gradient
#%% algorithm which solves, in the case of PAW calculations,
#%% a generalized eigenproblem (H.|Psi>=Lambda.S|Psi>).
#%% Three datasets are perfomed ; they must give the same
#%% total energies values (when converged).
