Abstract: Given matrix X and diagonal matrix Λ, the solutions (A,B) of the symmetric orthogonal symmetric matrices for inverse generalized eigenvalue problem AX=BXΛ are discussed. Based on singular values decomposition of a matrix, the general form of such solutions is established. Numerical examples were presented to illus trate the validity of the proposed method.

Key words: generalized eigenvalue, inverse problem, symmetric orthogonal symmetric matrix, singular value decomposition
