The square root of a matrix
WebNov 2, 2024 · In this paper, we study the asymptotic and transient dynamics of a predator–prey model with square root functional responses and random perturbation. Firstly, the mean square stability matrix is obtained from the stability theory of stochastic systems, and three stability indexes (root-mean-square resilience, root-mean-square … WebMay 29, 2024 · Square roots of matrices, where they exist, are far from unique. Given the 2×2 identity matrix, one square root is the identity matrix itself. Another is the negative of the identity matrix. Or just make either one element -1. Or the "interchange marrix" where the diagonal elements are zero and the nondiagonal elements 1. And so on.
