```Dear Users
I am currently engaged in writing a function to deal with
some discrete nonlinear system, but unfortunately I am a completely novice
as Mathematica programmer.  Can someone out there give some clue how
to implement a problem such as the following one, please?
y(t)=a*y(t-1)+b*y(t-2)+c*y(t-1)*y(t-1) ->  First how to code?
y(t)=A*y1(t) + B*y2(t) + C*y3(t) + .... -> I want to compare
the two expressions and solve for y1(t), y2(t) etc.

Any help will be appreciated.

Eduardo
