Nous proposons, dans ce travail, une nouvelle méthode de reconstruction de données basée sur la minimisation d'une fonctionnelle type écart en énergie. L'éfficacité de la méthode est illustrée par une application issue de la thermostatique.
We propose, in this Note, a new procedure for data completion based on the minimization of an energy like error functional. The efficiency of the proposed method is illustrated by a thermostatic application.
