1.引言
设n阶Jacobi矩阵为
Jn=〔a1 b1 b1 a2 b2……bn-1……bn-1 an〕,ai,bi∈R,且bi<0,i=1,2,…,n-1.
In this paper, an inverse eigenvalue problem of constructing a Jacobian matrix from its prescribed specially ordered defective eigenpairs and a principal subma-trix is considered. The necessary and sufficient conditions for the existence and uniqueness of the solution are derived. Two numerical algorithms and two numerical examples are given.
