Options for output of solve function with sequential variables

Ladies and Gents,

I'm working on a code which checks the order of a polynomial and then creates that number (n=order + 1) of unknown variables. I then create a system of n linear equations and solve them using the solve function.

My current issue is being able to output the results to a 'n' variable array and THEN access the variables in a for loop for substitution. I have a 1xn symbolic array, but when I attempt to equate solve to it, it ignores the array and creates a struct.

syms t
S = sym('S', [1 (order+1)]);
A = sym('A', [1 (order+1)]);

lhs=(myequationoft1); %These are symbolic equations my code generates
rhs=(myequationoft2); %Each is a function of symbolics t and S1,S2,...SN

eqns=sym(zeros(order+1,1)); %Creates symbolic array which I can assign the equations to...
for i=1:(order+1)
    eqns(i)=(subs(diff(lhs,(i-1)),t,0)==subs(diff(rhs,(i-1)),t,0)); 
    %Assigns the (i-1)th derivative of each equation evaluated at t=0 to eqns(i)
end

A=solve(eqns,S); %This is my issue.... Straight assignment creates a struct
%I want to be able to access the items (A.S1,A.S2,...A.SN) in a for loop

fn = fieldnames(A) ;
for n=1:length(fn)
  An = A.(fn{n});
  do something
end

This worked, thank you!
