1. Optimising the Choice of Interpolation Nodes with a Forbidden Region
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : We consider the problem of optimizing the choice of interpolation nodes such that the interpolation error is minimized, given the constraint that none of the nodes may be placed inside a forbidden region. Restricting the problem to using one-dimensional polynomial interpolants, we explore different ways of quantifying the interpolation error; such as the integral of the absolute/squared difference between the interpolated function and the interpolant, or the Lebesgue constant, which compares the interpolant with the best possible approximating polynomial of a given degree.
