Abstract

Described the problem of recovering from discrete data in general smooth function. The algorithms of data smoothing, providing a smooth pair of generalized, built according to the linearly independent functions, polynomials defined on the mating intervals analysis. The possibility of using for this purpose the methods of constrained optimization. As the objective function is used the quadratic loss function. The smoothness of the conjugation of polynomials is provided with equality constraints. It was established that in the absence of constraints of inequality type solution of the recovery can be obtained in explicit form. The validity of the developed algorithms on examples of the treatment of special test signals. The results indicate the possibility of their use for the analysis multiextremal dependencies, which include the intensity of the acoustic signals functioning technical systems.
