! Subroutine: psb_zgatherm
! This subroutine gathers pieces of a distributed dense matrix into a local one.

! Arguments:
! globx - cplx,dimension(:,:). The local matrix into which gather
18 years ago
! the distributed pieces.
! locx - cplx,dimension(:,:). The local piece of the distributed
18 years ago
! matrix to be gathered.
! desc_a - type(psb_desc_type). The communication descriptor.
! info - integer. Error code.
18 years ago
! iroot - integer. The process that has to own the
! global matrix. If -1 all
! the processes will have a copy.
