### Testing fsolve and anonymous function

I have got a need to solve equations repeatedly whose coefficients are changing with each iteration. MatLab function 'fsolve' is tested using function handle and anonymous function as follows.
s=[3 7 11];
d=[1 3 5];
%ans= (2,1), (5,2), (8,3)
for i=1:3
x0 = [-5; -5]; % Make a starting guess at the solution
myfun =@(x) [x(1) + x(2) - s(i);
x(1) - x(2) - d(i)];
[x,fval] = fsolve(myfun,x0)  % Call
end
