Abstract: The main objective of this paper is to present the time domain, frequency domain and stability analysis of linear systems represented by differential equations with complex-order derivatives ...

[t,P] = solve_riccati_ode(A,B,Q,R,[],PT,tspan) [t,P] = solve_riccati_ode(A,B,Q,R,S,PT,tspan) [t,P] = solve_riccati_ode(A,B,Q,R,S,PT,tspan) does the same as the syntax ...

Differential equations are equations that contain derivatives. The equations are used in calculus to describe relationships among one or more variables. A solution to any series of equations can be ...
