I run a function 'trim' and I got a message;
Maximum number of function evaluations exceeded;
increase OPTIONS(14)
Here is my code.
%.. Initial Conditions of Input Variables for Trim Calculation
% u = [ Throttle Aileron Elevator ]
u0 = [ 0.3 0 0 ]' ;
% x = [ VT AoA AoS P Q R Phi Theta Psi C1 C2 C3 ]
x0 = [ Vt_trim 0 0 0 0 0 0 0 Heading_Init 0 0 0 ]' ;
% y = [ Vt AoA AoS P Q R Phi Theta Psi C1 C2 C3 ]
y0 = [ Vt_trim 0 0 0 0 0 0 0 Heading_Init 0 0 0 ]' ;
%.. Compute Trim Codition for Controller
[ x_trim, u_trim, y_trim, xd_trim ] = trim('sys', x0, u0, y0, [], [], []) ;
What's the meaning of the message 'Maximum number of function evaluations exceeded; increase OPTIONS(14)'
and what should I do to solve my problem?

I couldn't reproduce the issue at my end, although I see increaes options as optimization parameter as defined in syntax of 5th and 6th option of trim function documentation, and other have used the optimization array in their respective work sucessfully as shown here, it may be helpful.
