Can someone please tell me is there a way to solve difference equation e.g:
y(k) = a1 * y(k-1) + a2 * y(k-2) + b0*u(k)
in Matlab using Symbolic Toolbox? I want to find explicit solution of this equation.
From this source, there are 2 methods:
Apply Z transform, solve for X(z), then find inverse Z transform look up tables if needed.
Write y(n)=r^n, to get the auxiliary equation, solve for homogeneous part first.
Bottom line is, there isn’t a good method to solve difference equations in Matlab now.
