摘要
A numerical procedure for an inverse problem of identification of an unknown source in a heat equation is presented. Approach of proposed method is to approximate unknown function by polygons linear pieces which are determined consecutively from the solution of minimization problem based on the overspecified data. A numerical examples are presented. (C) 2002 IMACS. Published by Elsevier Science B.V. All rights reserved.
