|
|
! psb_chkvect checks the validity of a descriptor vector desc_dec, the

! eventually computes the starting local indexes (iix,jjx) corresponding

|
|
! Finally, if an inconsistency is found among its parameters ix, jx,
|

! descdec and lldx, the routine returns an error code in info.
|
|
!
|
|
! Parameters:
|
|
! m - integer. The number of rows of the dense matrix X being operated on.
|
|
! n - integer. The number of columns of the dense matrix X being operated on.
|
|
! lldx - integer. The leading dimension of the local dense matrix X.
|
|
! ix - integer. X's global row index, which points to the beginning
|
|
! of the dense submatrix which is to be operated on.
|
|
! jx - integer. X's global column index, which points to the beginning
|
|
! of the dense submatrix which is to be operated on.

! desc_dec - integer(psb_ipk_),dimension(:). Is the matrix_data array.
