File: psb_sasb.f90 ! ! Subroutine: psb_sasb_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_s_vect_type) The matrix to be assembled. ! desc_a - type(psb_desc_type). The communication descriptor. ! info - integer. return code ! mold - type(psb_s_base_vect_type), optional A mold for the inner storage format ! scratch - logical, optional If true, allocate without checking/zeroing contents. !
