#%%   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).
