摘要
首先对Jacob i矩阵的特征值进行了分析,然后讨论了由一个特征对构造Jacob i矩阵的问题,得出了该问题在某一类集合中有解的充分必要条件,并给出了解的具体表达式.
The eigenanalysis of Jacobi matrix was given firstly and then the problem on the construction of Jacobi matrix from one eigenpairs was discussed. The necessary and sufficient conditions for the existence of the Jacobi matrix in some sets were gained and the formula of the solution was derived.
