　　In the context of nonlinear inverse problems,we present an efficient way to construct the linear subproblems of a Gauss-Newtonian iteration.The method is based on solving the forward problem in a high-dimensional parameter domain by using spectral methods,resulting in a numerical solution that depends explicitly on the parameters.As an example we study the inverse boundary value problem of a parabolic partial differential equation.
