This chapter explains the numerical methods used by the gyre frontend to solve the oscillation equations (similar approaches are followed in other frontends). Although it aims to be user-friendly, gyre is nevertheless a complex piece of software; thus, getting it to produce the ‘best’ results requires some degree of insight into the algorithms it uses to calculate mode eigenfrequencies and eigenfunctions.
