Subject: [Boost-commit] svn:boost r52147 - in branches/release/libs/numeric/ublas: doc doc/samples test test/common
From: guwi17_at_[hidden]
Date: 2009-04-02 18:36:42
Author: guwi17
Date: 2009-04-02 18:36:39 EDT (Thu, 02 Apr 2009)
New Revision: 52147
URL: http://svn.boost.org/trac/boost/changeset/52147
Log:
ublas/doc/samples/ex_triangular.cpp: added new example
ublas/doc/samples/Jamfile.v2: added build section for ex_triangular
ublas/doc/container_concept.htm: fixed wrong description of array_type
ublas/doc/triangular.htm: fixed lower/upper confusion and added link to ex_triangular
ublas/test/test_lu.cpp: added unit test for LU decomposition
ublas/test/triangular_access.cpp: added unit test for accessing triangular/symmetric matrices
ublas/test/triangular_layout.cpp: added unit test for testing storage layout of triangular/symmetric matrices
ublas/test/common/testhelper.hpp: support routines for new unit tests
ublas/test/CMakeLists.txt: added new tests (still experimental) test_lu, triangular_access. triangular_layout
ublas/test/Jamfile.v2:
added new tests (still experimental) test_lu, triangular_access. triangular_layout
disabled broken test7 (maybe a fix of boost::interval is needed, see #2473)
ublas/test/test71.cpp, ublas/test/test73.cpp, ublas/test/test7.cpp:
added first fixes to support boost::interval as scalar type
ublas/test/common/init.hpp:
initialize all matrices/vectors with floats instead of (unsigned) ints
this helps to fix broken test7 for boost::interval
