Linearity is the main assumption used in all fields of science. It gives a first order approximation to any problem under study and widely used in economics and other social sciences.
Many of the applications of linear algebra such as matrices, determinants, systems of equations and the eigenvalue problem can all be easily handled using MATLAB (MATrix LABoratory)
