Introduction to Systems and General Solutions to Systems
... If the n solutions form a fundamental set of solutions (in other words, if the yi are linearly independent solutions), then we call Ψ a fundamental matrix for the system. We have already seen that any solution to the system y′ = P (t)y must have the form Ψ(t)c where Ψ(t) is our fundamental matrix a ...
