2610	 Gauss Harmonic Interpolation Formulas	 Let R be an open bounded simply connected region in the x y -plane and let x y be a point in R. Assuming R is starlike with respect to x y we discuss a method for computing Gauss harmonic interpolation formulas for R and the point x y . Such formulas approximate a harmonic function at x y in terms of a linear combination of its values at certain selected points on the boundary of R. Such formulas are useful for approximating the solution of the Dirichlet problem for R. interpolation quadrature harmonic interpolation harmonic quadrature Dirichlet problem
