Hi there

My question concerns Difference Equations and MATLAB. I would like to
know how to properly input a difference equation into Matlab and graph
it, so that I could answer questions such as:

"For the following difference equation compute y1 to y4, find the
equilibrium and the solution, classify the equilibrium as stable or
unstable, describe the long-run behaviour and sketch the graph of the
equation:

y(t+1) = 20 - 3y(t), where y0 = 1"

Any help is much appreciated
Thanks
Patrick
