Abstract:

In order to analyze the accuracy of a fixed, finite-dimensional approximation space which is not uniform over its domain Omega, we define approximation error map, a description of how the error is distributed over Omega-not for a single test function but for a general class of such functions. We show how to compute such a map from the best approximations to an orthonormal basis of the target function space.
