1. Introduction Many science and engineering models have semi-inﬁnite domains, and a quick and effec-tive approach to ﬁnding solutions to such problems is valuable. The matrix exponential can be successfully used for solving systems of differential equations. Consider a system of linear homogeneous equations, which in matrix form can be written as follows: $\mathbf{X}’\left( t \right) = A\mathbf{X}\left( t \right).$ The general solution of this system is represented in terms of the matrix exponential as Linear differential equations. The matrix exponential has applications to systems of linear differential equations. (See also matrix differential equation.) Recall from earlier in this article that a homogeneous differential equation of the form ′ = has solution e At y(0). Solve a Simultaneous Set of Two Linear Equations.

### If I Taylor expand the matrix exponential it's an infinite series, so I'm not sure how to deal with that - is there a way to make $\hat{\rho(0)}$ into an exponential as well and simplify it that way? I also considered writing $\rho = \frac{1}{2}(I+a(t)X+b(t)Y+c(t)Z)$, and if I substitute that back into the original differential equation then I could find the coefficients by evaluating the
