+The Meschach Library is a numerical library of C routines for performing
+calculations on matrices and vectors. It is intended for solving systems of
+linear equations (dense and sparse), solve least squares problems,
+computing eigenvalues and eigenvectors, etc. We do not claim that it
+contains every useful algorithm in numerical linear algebra, but it does
+provide a basis on which more advanced algorithms can be built. The library
+is for people who know something about the C programming language,
+something of how to solve the numerical problem they are faced with but do
+not want to have the hassle of building all the necessary routines from the
+scratch. The library is not a loose collection of numerical routines but it
+comprises a coherent system. The current version is enhanced with many
+features comparing with previous versions. Since the memory requirements
+are nontrivial for large problems we have paid more attention to
+allocation/deallocation of memory.
