From d0451b7fb82f682779b6df799a7ba9128de266f6 Mon Sep 17 00:00:00 2001 From: Wolfgang Bangerth Date: Tue, 2 Jul 2013 19:10:53 +0000 Subject: [PATCH] Patch by Denis Davydov: Provide functions to unroll and re-roll indices of Tensor, much the same as we already have for SymmetricTensor. Add test. git-svn-id: https://svn.dealii.org/trunk@29918 0785d39b-7218-0410-832d-ea1e28bc413d --- tests/base/tensor_24.cc | 56 ++++++++++++++++++++++++++++++++ tests/base/tensor_24/cmp/generic | 16 +++++++++ 2 files changed, 72 insertions(+) create mode 100644 tests/base/tensor_24.cc create mode 100644 tests/base/tensor_24/cmp/generic diff --git a/tests/base/tensor_24.cc b/tests/base/tensor_24.cc new file mode 100644 index 0000000000..70ea6057d5 --- /dev/null +++ b/tests/base/tensor_24.cc @@ -0,0 +1,56 @@ +//---------------------------- tensor_24.cc --------------------------- +// $Id$ +// Version: $Name$ +// +// Copyright (C) 2006, 2008, 2009 by the deal.II authors +// +// This file is subject to QPL and may not be distributed +// without copyright and license information.
