Y_beta=Yv;
N_beta=Nv;
Delta_r = [s-Y_beta / u0, 1-Yr / u0; -1*N_beta, s- Nr];
D_beta = [YdeltaR/u0, 1- Yr/u0; NdeltaR, s- Nr];
dr_appro=vpa(det(D_beta) ./ det(Delta_r) , 3);
disp('Beta transfer function:')
disp(dr_appro)
%ROLL DYNAMICS
RDra=vpa(LdeltaA ./ (s .*(s-Lp)) ,3);
disp('Roll angle transfer function:')
disp(RDra)
This is the error I obtained:
Error using sym/subsindex (line 853)
Invalid indexing or function definition. Indexing must follow MATLAB indexing. Function arguments must be symbolic variables, and function body must be sym expression.
Error in sym/subsref (line 898)
R_tilde = builtin('subsref',L_tilde,Idx);
Error in Nicolas_Moujon_new (line 192)
dr_appro=vpa(det(D_beta) ./ det(Delta_r) , 3);
I don't know how to solve it ! I just have seen that it happens few times ago. I tried by myself but unsuccessfully.
Thank you very much in advance for your help !!

You've defined a variable named det in your code. Because of this you cannot use the det function. Attempting to call det (the function) will instead be interpreted as an attempt to index into det (the variable.)
Rename that variable.
