Recently I got stuck on performing such a work, which is substituting into matrices I've tried over "Subs()" but it seems to be having wrong output

{ x=[1 3 5 7 9];

n=2;

syms a; for i=1:n %row %n=2 for j=1:n %col %n=2

A(i,j)=(a^(2*(n)-i-j+2))

end

end

syms a; syms b;

for k=1 for l=1:n+1

C(k,l)=b*(a)^(n) n=n-k; %when = 2 ,C = [ x^2*y, x*y, y] end

end c=transpose(C)

% totalsub=0; totalsub=subs(A,a,x)

% g=poly2sym(A) % X=(inv(A))*(c)

} when a 3x3 matrix times with 3x1 matrix it should be 3x3 but.. Even at the subs part...

*No products are associated with this question.*

Opportunities for recent engineering grads.
