Consider a mountain that is perfectly described by the Gumbel s function ( ) = . The mountain is reconstructed by sampling ( surveying )
Consider a mountain that is perfectly described by the Gumbels function The mountain is reconstructed by sampling surveying points from it and interpolating all other points from the interpolant. To put it in context, assume you are a surveyor, and you want to minimize the number of points to sample and from which you should reconstruct the Runge Mountain as accurately as possible. Define the reconstruction error as where is the interpolation at in at intervals of Compare and discuss your results for the following methods of sampling and interpolation: a Polynomial interpolation any method using randomly sampled points, in Matlab, abarand is a random number on a b b Polynomial interpolation using equally spaced points c Polynomial interpolation using Chebyshev points, aba cos on ab for i to n d RBF interpolation any using equally spaced points use appropriate value for parameter e RBF interpolation using Chebyshev points
