! Subroutine: psb_ssprn
|
|
! Reinit sparse matrix structure for psblas routines: on output the matrix
|
|
! is in the update state.
|
|
!
|
|
! Arguments:
|
|
! a - type(psb_s_sparse_mat). The sparse matrix to be reinitiated.
|
|
! desc_a - type(psb_desc_type). The communication descriptor.
|
|
! info - integer. Return code.
|
|
! clear - logical, optional Whether the coefficients should be zeroed
|
|
! default .true.
