How can I solve the error "unable to convert to matrix form because the system does not seem to be linear"

I have 19 equations and 19 variables. I am trying to use equations to matrix to solve it, yet I get the error:
Error using mupadengine/feval_internal
Unable to convert to matrix form because the system does not seem to be linear.
T = eng.feval_internal('symobj::equationsToMatrix',eqns,vars);
Some of the variables in my equations are squared, for example:
eqn15=(ayAB)+((0.275.*sind(th)).*((OAP).^2))-((0.15.*cosd(th2)).*(al_AB))-((0.15.*sind(th2)).*((AB).^2))==0;
Are those squares the mistake? How could I solve a system of non-linear equations if necessary?
