The method of fundamental solutions (MFS) is a well-established boundary-type numerical method for the solution of certain two-and three-dimensional elliptic boundary value problems [1,2]. The basic ideas were introduced by Kupradze and Alexidze (see, e.g., [3]), whereas the present form of the MFS

Various physical problems lead to an ill-conditioned system of equations TX U in which the variancecovariance matrix of the measured Vector Uis known. To facilitate the solution of such equations. the following form of the quadratic optimization problem was introduced: join fQ (X) = XTCX + DX + F X
We describe a family of the rational solutions of the Zakharov-Schabat equations. This family is characterized by extremely simple superposition principle, following directly from the Darboux-invariance of the Zakharov-Schabat equations proved in the works [1,4]. Particularly we present an infinite
