Description: a C++ class that provides a unified meshfree basis function computation. Its capabilities include the computation of first order maximum entropy (maxent) basis functions and first order moving least square (mls) basis functions along with their derivatives. It is a generic code in the sense that it can compute the aforementioned basis functions in one, two and three dimensions with just one single code.

Description: template header that simplifies matrix-vector operations. Matrix-vector operations are designed for small matrices since it uses direct implementations. However, it can solve large sparse linear systems very efficiently due to its interface to TAUCS library.
