Dear Developers,

What is the difference between nr1, nr2, nr3 and nrx1, nrx2, nrx3
in the code? For all practical purposes they always seem to be
the same.

In PW/pwcom.f90 we find:

   nr1,           &! fft dimension along x
   nr2,           &! fft dimension along y
   nr3,           &! fft dimension along z
   nrx1,          &! maximum fft dimension along x
   nrx2,          &! maximum fft dimension along y
   nrx3,          &! maximum fft dimension along z

But when would nr1 differ from nrx1?

Thanks a lot!
Timo
