Abstract
A FORTRAN 77 program is presented which solves the Sturm-Liouville pro blem for a system of coupled second-order differential equations by th e finite element method using high-order accuracy approximations. The analytical and tabular forms of giving the coefficients of differentia l equations are considered. Zero-value (Dirichlet) and zero-gradient ( Neumann) boundary conditions are also considered.
