On the adaptive spectral approximation of functions using redundant sets and frames
Vincent Coppé, Daan Huybrechs
The approximation of smooth functions with a spectral basis typically leads to rapidly decaying coefficients where the rate of decay depends on the smoothness of the function and v…
Efficient function approximation on general bounded domains using wavelets on a cartesian grid
Vincent Coppé, Daan Huybrechs
Fourier extension is an approximation method that alleviates the periodicity requirements of Fourier series and avoids the Gibbs phenomenon when approximating functions. We describ…
The AZ algorithm for least squares systems with a known incomplete generalized inverse
Vincent Coppe, Daan Huybrechs, Roel Matthysen +1
We introduce an algorithm for the least squares solution of a rectangular linear system , in which may be arbitrarily ill-conditioned. We assume that a complementary matr…
Efficient function approximation on general bounded domains using splines on a Cartesian grid
Vincent Coppé, Daan Huybrechs
Functions on a bounded domain in scientific computing are often approximated using piecewise polynomial approximations on meshes that adapt to the shape of the geometry. We study t…
Pointwise and uniform convergence of Fourier extensions
Marcus Webb, Vincent Coppé, Daan Huybrechs
Fourier series approximations of continuous but nonperiodic functions on an interval suffer the Gibbs phenomenon, which means there is a permanent oscillatory overshoot in the neig…
