interface)
use elpa1
success =

With the definitions of the input and output variables:
integer, intent(in)
na: Order of matrix

complex*16, intent(inout)
a: locally distributed part of the matrix

triangule needs to be set. The lower triangle is not referenced
integer, intent(in)
lda: leading dimension of locally distributed matrix

Inverts a upper triangular matrix a. The ELPA communicators
mpi_comm_rows
and
mpi_comm_cols are obtained with the
elpa_get_communicators(3) function.
This function is part of the legacy API of the ELPA library. Better use the
current API.
Old interface:
elpa_get_communicators(3)
elpa_invert_trm_real_single(3)
elpa_invert_trm_complex_double(3)
