Symmetric approximation
WebAn iteration method is constructed to solve the linear matrix equation AXB=C over symmetric X. By this iteration method, the solvability of the equation AXB=C over symmetric X can be determined automatically, when the equation AXB=C is consistent over symmetric X, its solution can be obtained within finite iteration steps, and its least-norm symmetric … WebApr 30, 2024 · The main objective of this paper is to study an approximation of symmetric tensors by symmetric orthogonal decomposition.

We introduce a method to obtain the envelopes of eccentric orbits in vacuum axially symmetric potentials, Φ ( R, z), endowed with z -symmetry of reflection, as it is usual in discoidal galaxies and other spheroidal-shaped astrophysical objects. By making the transformation z → a + a 2 + z 2, with a > 0, we compute the resulting ...
WebFeb 10, 2024 · An enormous amount of literature has been devoted to the study of symmetric positive semi-definite (SPSD) kernels, where Nystrom methods compute a low-rank approximation to the kernel matrix via choosing landmark points. In this paper, we study the Nystrom method for approximating both symmetric indefinite kernel matrices … WebThe Wilson score interval is an improvement over the normal approximation interval in multiple respects. It was developed by Edwin Bidwell Wilson (1927). Unlike the symmetric normal approximation interval (above), the Wilson score interval is asymmetric.It does not suffer from problems of overshoot and zero-width intervals that afflict the normal interval, …
