Can't find references for lqr.m

Hi all, I'm currently studying LQR control, specially on the Riccati Solver. When I was looking into lqr document Linear-Quadratic Regulator (LQR) design - MATLAB lqr (mathworks.com), I can't find the references for lqr.m or the references where lqr.m solves Riccati Equations.

Where could I find those files? It would be perfect to send links or sites.

Thanks a lot!

Hi Bruno, thanks for the link.

Maybe there is a misunderstanding, but I'm actually looking for a reference such as:

At the bottom of (Not recommended) Continuous-time algebraic Riccati equation solution - MATLAB care (mathworks.com), the "References" (attached figure) is what I'm trying to find.

If it is in the link you gave, then I sorry that I must have overlooked. Could you kindly point out where I can find it?

Thanks!

Indeed I missunderstand what you ask for.

In the end of the dco page there is the description of the algorithm for solving Riccati equation.Maight be it is too simple for a reference paper to be written and publsihed.
