The recent development of computer algebra systems and symbolic programming languages gives new insights into scientific computing: symbolic computations will now be able to serve as a substitute for numerical computations. The Galerkin procedure applies to boundary value problems from continuum physics. It is based upon a variational formulation of the initial problem and consists in computing approximate solutions as linear combinations of previously chosen basis functions. Thanks to computer algebra, symbolic basis functions can be manipulated, thus providing an alternative to the finite element technique.
