| Abstract: | 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. |
