how do you use a for loop to maximize a variable in a system of equations?
such as 3x + 2y = cos phi
4x - 3y = 2cos phi
find a phi that maximizes x for instance

I would not use a for loop.
syms x y phi
[solx, soly] = solve(3*x+2*y == cos(phi), 4*x-3*y = 2*cos(phi), x, y);
bestphi = solve(diff(solx(1),phi),phi);
