Stiﬀness and Mass Matrices book
In this chapter, we use the three-dimensional mesh of tetrahedra, along with the three-dimensional polynomials, to form the so-called stiﬀness and mass matrices, which are particularly useful in scientiﬁc computing  . In fact, the mathematical objects developed throughout the book are combined here to form an advanced practical tool in applied science and engineering.
