The way boundary conditions are imposed when applying Chebyshev collocation methods to Poisson and biharmonic-type problems in rectangular domains is investigated. It is shown that careful selection of the number of collocation points leads to a linear system of n linearly independent equations in n unknowns. © 1991 Plenum Publishing Corporation.
