 <h2>Frequently Asked Questions</h2>
 
+<p>Q: Should I use uBLAS for new projects?<br/>
+A: At the time of writing (09/2012) there are a lot of good matrix libraries \
available, e.g.,  +<a href="http://www.simunova.com" target="_blank">MTL4</a>,
+<a href="http://arma.sourceforge.net" target="_blank">armadillo</a>,
+<a href="http://eigen.tuxfamily.org" target="_blank">eigen</a>. uBLAS offers a \
stable, well tested set of vector and  +matrix classes, the typical operations for \
linear algebra and solvers for triangular systems of equations. uBLAS offers  +dense, \
structured and sparse matrices - all using similar interfaces. And finally uBLAS \
offers good (but not outstanding)  +performance. On the other side, the last major \
improvement of uBLAS was in 2008 and no significant change was committed  +since \
2009. So one should ask himself some questions to aid the decision: \
<i>Availability?</i> uBLAS is part of boost  +and thus available in many \
environments. <i>Easy to use?</i> uBLAS is easy to use for simple things, but needs \
decent +C++ knowledge when you leave the path. <i>Performance?</i> There are faster \
alternatives. <i>Cutting edge?</i> uBLAS  +is more than 10 years old and missed all \
new stuff from C++11. </p> +
 <p>Q: I'm running the uBLAS dense vector and matrix benchmarks. Why do I see a \
significant performance difference  between the native C and library \
implementations?<br />  A: uBLAS distinguishes debug mode (size and type conformance \
checks enabled, expression templates disabled) and release
