Since the Riccati equation is a first-order ordinary differential equation, you can do this easily with any of the ODE solvers available in MATLAB such as "ode45".
The trick is to find the solution backwards in time.
As an example, let us consider the following example. Let the Riccati equation be given by
y'(t) = q0 + q1*y(t) + q2*y(t)^2, y(tf) = yf
where q0, q2 are non-vanishing constants (these may be nontrivial functions of t, the fact that they are chosen to be constant is just for simplicity). The second line is the boundary condition that at the end time tf, the value of the solution must be yf. I have chosen, in particular, tf = 2 and yf = 1 in the example code below.
function riccatiEquationRunner() par = [1;2;1]; % q0, q1, and q2 yf = 1; ti = 0; tf = 2; opt = odeset('AbsTol',1.0e-07,'RelTol',1.0e-07); [t,y] = ode45( @riccatiEquation, [tf,ti], yf ,opt, par); % Visualize plot(t,y)
