《Dynamical Systems with Applications using MATLAB》一书是用来介绍离散和连续系统下动态非线性系统理论的经典教材（分形、混沌、非线性系统）。这里的附件包含

% Chapter 1 - Linear Discrete Dynamical Systems.
% Program 1a - Solving Recurrence Relations.
% Symbolic Math toolbox required.
% Copyright Birkhauser 2004. Stephen Lynch.

% Solving a first order recurrence relation (Example 1).
% Call a Maple command from the Symbolic Math toolbox.
xn=maple('rsolve({x(n+1)-(1+(3/(100)))*x(n),x(0)=10000},x)')
n=5
savings=vpa(eval(xn),7)

%Solving a second order recurrence relation (Example 2(i)).
clear  
xn=maple('rsolve({x(n+2)-x(n+1)-6*x(n),x(0)=1,x(1)=2},x)')

% Solving a characteristic equation (Example 2(iii)).
syms lambda
CE=lambda^2-lambda+1 
lambda=solve(CE)
