Spectral interpolation at the nodes of spherical Lissajous curves
Version: 0.4 (01.02.2018)
Written by Wolfgang Erb
The package LSphere contains a Matlab-implementation to calculate a spectral interpolation on the sphere from data given on the nodes of spherical Lissajous curves. The description of the spherical Lissajous curves, the Lissajous node sets and the spectral interpolation scheme can be found in .
To test the package use main_example.m
To plot the spherical Lissajous curve and its intersection points use Lissajous_example.m
To plot the Lagrange functions of the interpolation scheme use Lagrange_example.m
For an application of the interpolation scheme in estimating the rotation of objects try navigator_nls_example.m
