Abstract :
The transition matrix \\varphi corresponding to the n -dimensional matrix A can be represented by \\varphi (t) = g_{1}(t)I + g_{2}(t)A + ... + g_{n}(t)A^{n-1} , where the vector g^{T} = (g_{1}, ... , g_{n}) is generated from \\dot{g}^{T} = g^{T}A_{c}, g^{T}(0) = (1, 0, ... , 0) and Acis the companion matrix to A . The result is applied to the covariance differential equation \\dot{C} = AC + CA^{T} + Q and its solution is written as a finite series. The equations are presented in a form amenable for implementation on a digital computer.
