Abstract
We have studied the concept of quadratic form and the definition of positive-definite matrix is introduced.In fact,positive definite matrix is a kind of very important matrix in algebra, it can be applied to the value of extreme and eigenvalue,the prove of inequality and stability analysis of system.This paper firstly introduced the definition of real symmetric matrices,and 7 theorems are given to determine positive definite matrix,then the related properties of positive definite matrix were summarized, the positive definite matrix in the application of proving inequality,function extreme and so on were illustrated finally.
Keywords:properties,determinant,real symmetric, positive-definite matrix.
