Then, the operational matrix of integration together with the product and coefficient matrices are presented. They are used to transform linear differential equation systems to a set of linear algebraic equations. Finally, numerical examples are given.</dc:description><dc:publisher>American Institute of Physics Inc.</dc:publisher><dc:date>2014</dc:date><dc:type>Conference Object</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/15663</dc:identifier><dc:identifier>https://doi.org/10.1063/1.4893849</dc:identifier><dc:identifier>978-073541247-7</dc:identifier><dc:identifier>0094-243X</dc:identifier><dc:language>en</dc:language><dc:relation>AIP Conference Proceedings</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/conferenceObject</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/15663</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
