using fsolve with nonlinear equations arise in loops

Consider the following problem

Agg=@(co) [co(1)+co(2)-3; co(1)-co(2)-1];

r=fsolve(Agg,[0 0 ]);

This solve the system and obtain the results easily. But if we want the Agg function calculated in a previous loop e.g from an algebraic equation so I can not define variables as co(1) co(2) etc.

the problem get the form

co=sym('co',[1 2]);

Agg(1)=int(...)

Agg(2)=int(...)

r=fsolve(Agg,[0 0 ]);

but this dont work as Agg takes the form [co1+co2-3; co1-co2-1] but matlab needs to be [co(1)+co(2)-3; co(1)-co(2)-1].

What should I do to rplace co1 by co(1). subs and others dont work as co is not define befor

r=fsolve(matlabFunction(Agg),[0 0  ]);

Thanks dear Matt

but we have also the same error "Not enough input arguments"

[Matt J]

r=fsolve(matlabFunction(Agg,'Vars',{[co1,co2]}),[0 0]);

Really Thanks dear Matt. I apreciate your kind and valuable help
