i tired to use the "solve" command to solve a known couple ricatti equation, however matlab said a solution could not be found. ARE THERE OTHER WAYS OF SOLVING COUPLED RICATTI EQUATIONS USING MATLAB?

V=[0.1 0.1];

A=diag(V);

B1=[0;1];

B2=[2;0];

f=[1.62 0.095];

h=[0.81 0.705];

E1=diag(f);

E2=diag(h);

g=[47.6 0.8];

Q1=diag(g);

i=[15.6 10];

Q2=diag(i);

S= solve(P1*A+A'*P1-P1*(B1*B1')*P1-P1*(B2*B2')*P2-P2*(B2*B2')*P1-P2*(B2*B2')*P2+Q1+2E1==0, P2*A+A'*P2-P2*(B2*B2')*P2-P2*(B1*B1')*P1-P1*(B1*B1')*P2-P1*(B1*B1')*P1+Q2+2E2==0);
