块Jacobi矩阵正定的充要条件

Necessary and Sufficient Condition for the Positive Definite of Lump Jacobi Matrix

块Jacobi矩阵在工程中有很重要的应用。文章研究了块Jacobi矩阵的正定性,并将文献[1]中的一个结论进行了推广,得到了块Jacobi矩阵正定的一个充分必要条件。

Jacobi Matrix is very important in engineering. The Positive Definite Properties of Lump Jacobi Matrix are studied, one of the conclusions in document[1] is generalized, the necessaryand sufficient condition for the Positive Definite of Lump Jacobi Matrix is gained.
