The inverse square root of a matrix plays a role in the computation of an optimal symmetric orthogonalization of a set of vectors. We suggest two iterative techniques to compute an inverse square root of a given matrix. The two schemes are analyzed and their numerical stability properties are ...
摘要: In this paper we present an explicit formula to find a square root of certain class of matrices using Cayley-Hamiliton Theorem. Our formula extend and generalize the corresponding approach for 22 matrix. Also, some examples are given in support of our method.被引量: 2 ...
By utilizing the square root of a matrix approach, a method of generating the solution to a steady-state matrix Riccati type equation (under certain restrictions) is presented. This approach not only yields a closed form expression for the Riccati solution, but also converts the original Riccati...
