pdgstrs/pzgstrs Solve systems of distributed linear equations
routines.
B
(input/output)
On entry, the distributed right-hand side matrix of the
possibly equilibrated system. On exit, the distributed
solution matrix Y of the possibly equilibrated system if
info=0.
m_loc
(input)(local)
The local row dimension of matrix B.
fst_row
(input)(global)
The row number of B’s first row in the global matrix.
ldb
(input)(local)
The leading dimension of matrix B.
nrhs
(input)(global)
The number of right-hand sides.
SOLVEstruct
(output)(global)
Contains the information for the communication
during the solution phase.
stat
(output)
Record the statistics about the triangular solves.
info
(output) = 0
: successful exit
< 0: if info= -i, the i-th argument had an illegal value.
