! File: psb_casb.f90
|
|
!
|
|
! Subroutine: psb_casb_vect, _vect_r2 and _multivect
|
|
! Assembles a dense vector, an array of vectors or a multivector
|
|
! for PSBLAS routines.
|
|
! Since the allocation may have been called with the desciptor
|
|
! in the build state we make sure that X has a number of rows
|
|
! allowing for the halo indices, reallocating if necessary.
|
|
! We also call the halo routine for good measure.
|
|
! However, sometimes we need to create temporary vectors whose contents
|
|
! will be initialized through some subsequent call to geaxpby or similar;
|
|
! for this situation we provide the SCRATCH flag.
|
|
!
|
|
!
|
|
! Arguments:
|
|
! x - type(psb_c_vect_type) The matrix to be assembled.
|
|
! desc_a - type(psb_desc_type). The communication descriptor.
|
|
! info - integer. return code
|
|
! mold - type(psb_c_base_vect_type), optional A mold for the inner storage format
|
|
! scratch - logical, optional If true, allocate without checking/zeroing contents.
|
|
! default: .false.
