Can any one help me regarding how to optimize matrix Y & obtain F,Xm using Fmincon in the matlab code written below?

j=-1;

Xcs1=1/(2*3.14*0.2);
Xcp2=1/(2*3.14*0.3);
Xcs2=1/(2*3.14*0.4);  
Z1=((Rr/F-v)+j*Xr);
Z2=-j*Xm;
Z3=-j*Xlm;
Z4=((R2/F)+j*X2);
Z5=(R1/F)+j*X1;
Z6=(-j*Xcp2/F*2);
Z7=((Rl2/F)+j*(Xl2-(Xcs2/F*2)));
Z8=(-j*Xcp2/F*2);
Z9=((Rl1/F)+j*(Xl1-(Xcs1/F*2)));
fprintf('Impedances\n Z1 = %d \n Z2 = %d \n Z3 = %d \n Z4 = %d \n Z5 = %d \n Z6 = %d \n Z7 = %d \n Z8 = %d \n Z9 = %d \n', Z1, Z2, Z3, Z4, Z5, Z6, Z7, Z8, Z9);
