Purpose


PZGSTRS solves a system of distributed linear equations
A*X = B with a general N-by-N matrix A using the LU factorization
computed by PZGSTRF.
If the equilibration, and row and column permutations were performed,
the LU factorization was performed for A1 where
    A1 = Pc*Pr*diag(R)*A*diag(C)*Pc^T = L*U
and the linear system solved is
    A1 * Y = Pc*Pr*B1, where B was overwritten by B1 = diag(R)*B, and
the permutation to B1 by Pc*Pr is applied internally in this routine.

Arguments


n      (input) int (global)
       The order of the system of linear equations.

LUstruct (input) zLUstruct_t*
       The distributed data structures storing L and U factors.
       The L and U factors are obtained from PZGSTRF for
       the possibly scaled and permuted matrix A.
       See superlu_ddefs.h for the definition of 'zLUstruct_t'.
       A may be scaled and permuted into A1, so that
       A1 = Pc*Pr*diag(R)*A*diag(C)*Pc^T = L*U

grid   (input) gridinfo_t*
       The 2D process mesh. It contains the MPI communicator, the number
       of process rows (NPROW), the number of process columns (NPCOL),
       and my process rank. It is an input argument to all the
       parallel routines.
       Grid can be initialized by subroutine SUPERLU_GRIDINIT.
       See superlu_defs.h for the definition of 'gridinfo_t'.

B      (input/output) doublecomplex*
       On entry, the distributed right-hand side matrix of the possibly
       equilibrated system. That is, B may be overwritten by diag(R)*B.
       On exit, the distributed solution matrix Y of the possibly
       equilibrated system if info = 0, where Y = Pc*diag(C)^(-1)*X,
       and X is the solution of the original system.

m_loc  (input) int (local)
       The local row dimension of matrix B.

fst_row (input) int (global)
       The row number of B's first row in the global matrix.

ldb    (input) int (local)
       The leading dimension of matrix B.

nrhs   (input) int (global)
       Number of right-hand sides.

SOLVEstruct (input) zSOLVEstruct_t* (global)
       Contains the information for the communication during the
       solution phase.

stat   (output) SuperLUStat_t*
       Record the statistics about the triangular solves.
       See util.h for the definition of 'SuperLUStat_t'.

info   (output) int*
    = 0: successful exit
    < 0: if info = -i, the i-th argument had an illegal value
