Our goal in this paper is to derive an efficient algorithm for solving the IEP especially when n is large. Two examples were mentioned in Friedland, Nocedal, and Overton [4] where one needs to solve IEP with large n: the inverse Sturm Liouville problem where n is the number of grid points and in nuclear spectroscopy where n is the number of measurements. We note that the IEP can be formulated as a system of nonlinear equations f (c) j ( 1 (c) Gamma 1 ; ....

Our goal in this paper is to derive an efficient algorithm for solving the IEP. In Friedland, Nocedal, and Overton [3], the IEP is solved by applying a Newton like method, where in each Newton iteration (the outer iteration) we need to solve two linear systems: i) the inverse power method to find the approximate eigenvectors of the current iterate, and (ii) to solve the approximate Jacobian equation.

The convergence analysis is given in x4 and we present our numerical results in x5. 2 The Newton Like Method In this section, we briefly recall the Newton and Newton like methods for solving the IEP.

....is as prescribed. Finding such a matrix C (when it exists) for a given D is known as the multiplicative inverse eigenvalue problem [4] and can be solved in closed form for systems of dimension up to three. For higher dimension, finding solutions is more difficult and even state of the art methods [5] are unsatisfactory: among other things, they are iterative and global convergence is not assured. Moreover, general conditions for a solution to exist are not known. A better strategy is to use the approach in [6] see pages 69 75) for constructing the model of a simply connected mass spring ....

....subgradients of the sum of the first few eigenvalues of a symmetric matrix and formulates optimality conditions for this problem. In the same spirit as Fletcher, Overton [Ove88] studies the largest eigenvalue of a symmetric matrix as a convex, but nondifferentiable function. Based on earlier work [FNO87], in [Ove88] he derives a quadratically convergent algorithm for the problem of minimizing the largest eigenvalue of an affinely constrained matrix. This work is further extended in [Ove92] where both second order methods based on sequential quadratic programming, and first order methods based on ....

....minmax optimization techniques (e.g. MO80] cannot be applied. Suggestions 2 for transforming the problem into a standard nonlinear programming form by means of determinants have been made [GT88] but these methods perform poorly [Pan89] for other comments on the use of determinants, see [FNO87] In the example given above, the maximum eigenvalue is convex in x. This is true in general when A depends linearly on x, since the Rayleigh principle can be used to show that the maximum eigenvalue is a convex function of the matrix elements. Because of this fact, it has been recognized for ....
....problems arising in structural engineering. In [Ove88] a quadratically convergent algorithm was given to solve the model problem, using a dual matrix formulation of the optimality conditions to fully exploit the nonsmooth problem structure. Two papers which greatly influenced this work were [FNO87,Fle85] Numerical examples were given, demonstrating quadratic convergence to nonsmooth solutions. The assumption was made that A(x) was affine, although it was indicated that this was not essential for the main ideas to apply. The reason for this is that the eigenvalues are nonsmooth, nonlinear ....

If t = 2, the second through fourth rows of E give a linearization of the appropriate set of three nonlinear equations imposing the coalescence of 1 (oe j) and 2 (oe j) see [16]. The common linearized value, 1 (oe) is maximized, subject to the given constraints. Theorem 6.2.
