Nonnegative Solutions to Systems with Symmetric Circulant Matrix
Yu. S. Volkov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
For a system with symmetric circulant matrix, conditions on the right-hand side vector which ensure the positivity of the solution to the system are found. As an application of the results obtained, the problem of positive spline interpolation of positive functions on uniform grids is studied.
