1. The problem statement, all variables and given/known data So the first part of the problem asks us to solve for the state transition matrix, which I found to be: Phi(t) = [2 0 0; (2-e^-t) e^-t 0; 0 0 e^-2t]; I need to find the matrix A, which I assume can be done with the following relation: Phit(t) = e^(At) where A is also a matrix 2. Relevant equations Need to solve for A. Not sure how to solve this and what properties hold when matrices are concerned. 3. The attempt at a solution I initially thought to diagonlize Phi(t) but didnt really get anywhere.
