! This routine does two things:
|
|
! 1. Computes the transpose of the prolongator Prol and stores
|
|
! it explicitly into Restr
|
|
! 2. Computes AC = P^T A P
|
|
!
|
|
! Yes, doing two things at once is against received wisdom, but we are

! trying to save time in the build procedure; maybe we will revisit this
