The Electronic Journal of Linear Algebra (ELA), a publication of the International Linear Algebra Society (ILAS), is a refereed all-electronic journal that welcomes mathematical articles of high standards that contribute new information and new insights to matrix analysis and the various aspects of linear algebra and its applications. ELA is a JCR ranked journal, and indexed by MathSciNet, ZentralBlatt, and Scopus.  ELA is completely free for authors/readers; and  ELA is built on the selfless contributions of its authors, referees and editors.
