 Dear Matteo 
      In the example of caculate the value of U,after I extract the occupatin numbers ,I execute the  ucalc_sc1 file ,and gave these errors :
          /tmp/ifortLWE1zB.o(.text+0x742e): In function `invmat_':
              : undefined reference to `dgetrf_'
         /tmp/ifortLWE1zB.o(.text+0x744e): In function `invmat_':
              : undefined reference to `dgetri_'
       ucalc_sc1.j: line 32: ./r.x: don't have that file or list
       grep: Umat.out: don't have that file or list
                 .......................
I want to know what's wrong with it and how I should modify it .Thank you !
