Orthogonal projections of multidimensional ellipsoids – VI – considerations and vector generation for numerical experiments in four dimensions
After our recent excursion to Schur complements, some readers may wish to get a visual confirmation of our rather theoretical results. As usual in this blog, we will perform some numerical experiments. To get started, I will restrict my efforts to the projection of an ellipsoid from a 4-dimensional Euclidean space down to three- and two-dimensional sub-spaces. In a later… Read More »Orthogonal projections of multidimensional ellipsoids – VI – considerations and vector generation for numerical experiments in four dimensions
