【Abstract】 In this paper,an inverse eigenvalue problem for symmetric anti-bidiagonal matrix is dis- cussed.It shows that an n degree symmetric anti-bidiagonal matrix can be determined if an eigenvalue of the symmetric anti-bidiagonal matrix and the eigenvalues of two n-1 degree submatrices are known. Numerical examples are also provided.更多还原
