摘　　要：针对实际问题中经常遇到广义特征值的逆问题 ,研究了一类对称正定及半正定的左右逆特征问题 ,给出了这类问题的对称解 ,对称正定解 ,对称半正定解存在的充要条件与其解的表达式 .It has always been met the generalized inverse eigenvalue problem in accordence with the practical problems. In this paper, a class of left and right inverse eigenvalue problems for positive definite symmetric and positive semidefinite symmetric matrices is investigated. The conditions of existing solutions with necessity and sufficency and their expression of solutions of symmetric, positive definite and positive semidefinite solutions for this problem are given.
