摘要
构造了一个对称正定矩阵,矩阵元素与组合数有关,讨论了该矩阵的一些性质.根据MATLAB数值计算的结果,提出了该矩阵有关特征值性质的一些猜想.
This paper constructs a symmetric positive definite matrix, and the matrix elements are relevant to the combinational number, some properties of the matrix are discussed. According to the numerical calculation results of MATLAB, some guesses about the properties of the matrix eigenvalue have been put forward.
