grh.mur.at - C++ http://grh.mur.at/taxonomy/term/16/0 en Matrix Library Benchmark Follow-Up http://grh.mur.at/blog/matrix-library-benchmark-follow <p>It seems that many people start using the <a href="http://flens.sourceforge.net/">flens</a> C++ matrix library for scientific computation because of my <a href="http://grh.mur.at/publications/sparse-matrix-library-benchmark">Sparse Matrix Library Benchmark</a> article. This blog post should be a small add on and discusses possible difficulties with flens.</p> <p><strong>UPDATE: flens changed very much in 2012</strong> - see comment #3 by Michael Lehn! Now it is also header only like Eigen, so everything which is written here <strong>should be re-evaluated</strong>!</p> <h1>Problems with flens</h1> <p><a href="http://grh.mur.at/blog/matrix-library-benchmark-follow" target="_blank">read more</a></p> benchmark C C++ english blog sparse matrix Fri, 03 Jul 2009 22:01:46 +0000 grh 160 at http://grh.mur.at Sparse Matrix Library Benchmark http://grh.mur.at/publications/sparse-matrix-library-benchmark <div class="field field-type-number-integer field-field-year"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Year:&nbsp;</div> 2007 </div> </div> </div> <div class="field field-type-text field-field-authors"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Authors:&nbsp;</div> Georg Holzmann </div> </div> </div> <div class="field field-type-text field-field-pubtype"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Type:&nbsp;</div> Technical report </div> </div> </div> <div class="field field-type-text field-field-publisher"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Publisher:&nbsp;</div> <p>Internet Publication</p> </div> </div> </div> <div class="field field-type-text field-field-abstract"> <div class="field-label">Abstract:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> <p><center><strong>Important: please also look at the <a href="http://grh.mur.at/blog/matrix-library-benchmark-follow">Matrix Library Benchmark Follow-Up</a> !</strong></center></p> <p>This report presents benchmarks of C++ scientific computing libraries for small and medium size sparse matrices.</p> <p>Be warned: these benchmarks are very specialized on a neural network like algorithm I had to implement.
