SYNOPSIS

11   FORTRAN INTERFACE
12       use elpa1
13       success = elpa_invert_trm_complex_double (na, a, lda, nblk, matrixCols,
14       mpi_comm_rows, mpi_comm_cols, wantDebug)
15
16       With the definitions of the input and output variables:
17
18       integer, intent(in)        na:            Order of matrix a
19       complex*16,  intent(inout) a:             locally distributed part of
20       the matrix a. The local dimensions are lda x ldaCols. Only upper
21       triangule needs to be set. The lower triangle is not referenced
22       integer, intent(in)        lda:           leading dimension of locally
23       distributed matrix a
24       integer, intent(in)        nblk:          blocksize of cyclic
25       distribution, must be the same in both directions
26       integer, intent(in)        matrixCols:    number of columns of locally
27       distributed matrices a
28       integer, intent(in)        mpi_comm_rows: communicator for
29       communication in rows. Constructed with elpa_get_communicators(3)
30       integer, intent(in)        mpi_comm_cols: communicator for
31       communication in colums. Constructed with elpa_get_communicators(3)
32       logical, intent(in)        wantDebug:     if .true. , print more debug
33       information in case of an error

DESCRIPTION

66       Inverts a upper triangular matrix a. The ELPA communicators
67       mpi_comm_rows and mpi_comm_cols are obtained with the
68       elpa_get_communicators(3) function.
69       This function is part of the legacy API of the ELPA library. Better use
70       the current API.
