Spectral collocation and reconstruction methods have been widely studied for periodic functions using Fourier expansions. We investigate the use of modified Fourier series for the approximation and collocation of $d$-variate non-periodic functions with frequency support on a hyperbolic cross. We show that rank-$1$ lattice points can be used as collocation points in the approximation of non-periodic functions and these lattice points can be constructed by a component-by-component algorithm.status: publishe
