Abstract. In this paper, Let the matrix 𝐴 ∈ 𝐶𝑛×𝑛 with Ind (𝐴) = 𝑘, we first construct two bordered matrices based on [32], which gave a method for computing the null space of 𝐴𝑘 by applying ...

For a symmetric correlation matrix, the Inverse Correlation Matrix table contains the inverse of the correlation matrix, as shown in Figure 40.14. The diagonal elements of the inverse correlation ...
