A Krylov subspace algorithm for multiquadric interpolation in many dimensions
We consider the version of multiquadric interpolation where the interpolation conditions are the equations s(xi ) = fi , i = 1, 2, . . . , n, and where the interpolant has the form s(x) = ∑n j=1 λ j (‖x − x j‖ + c2)1/2 + α, x ∈ Rd , subject to the constraint ∑nj=1 λ j = 0. The points xi ∈ Rd , the right-hand sides fi , i = 1, 2, . . . , n, and the constant c are data. The equations and the cons...
متن کاملNumerical Solution of Natural Convection in a Vertical Channel.
Natural convection between vertical parallel plates occurs frequently in applications such as solar collectors and cooling of electronic instruments. The problem is a two dimensional developing buoyant flow. In this work, the two dimensional conservation equations are solved numerically for constant wall temperature and constant wall heat flux. The results for the local Nusselt number at the du...

15 صفحه اولA Fast Treecode for Multiquadric Interpolation with Varying Shape Parameters
A treecode algorithm is presented for the fast evaluation of multiquadric radial basis function (RBF) approximations. The method is a dual approach to one presented by Krasny and Wang, which applies far-field expansions to clusters of RBF centers (source points). The new approach clusters evaluation points instead and is therefore easily able to cope with basis functions that have different mul...
