MATLAB: Error with division of a matrix by a vector

Question

This is the part where the error occurs and it reads : "Error using ./ Matrix dimensions must agree."

These are the sizes of F2 and J2.

 size(F2)
ans =
  122     1
 size(J2)
ans =
   120   122

Is this possible to divide a matrix by a vector like this? J2 also has many 0 components. Any help will be appreciated. Thanks!

%20 newtons iteration
for i=20
[F1,F2,J1,J2]=thomas_newton(s,tm);
 delta_s=-F2'./J2';
 s=s+delta_s;
if norm(delta_s)<tol
    break
end
end

a=randi(10,1,10)
b=randi(10,10,12)
