The density-matrix renormalization group (DMRG) has been recently developed and has been widely used for calculations of electronic and magnetic systems in low dimensions. Its success is due to the fact that it is able to reach, with high precision, larger system sizes than those that can be obtained with exact diagonalization, allowing for a better study of the thermodynamic limit. In this article we describe the method for both, static and dynamical properties and we briefly analyze some of its applications.
