MATLAB: Here simple code keeps freezing the matlab, guess why

bugbusyfrozenfsolvefzeroloopsolve

Hi, the following code keeps my matlab freezed(busy). And it never get solved!
y=[9048;4807;3393;2686;2262;1980;1778;1626;1508];
z=[22187;11787;8321;6587;5547;4854;4359;3988;3699];
beta=0.985^2;
alpha=0.3;
gamma=0.03;
phi=roundn([2.077869902373392 2.560745705954086], -3);
R=3026;
syms x;
eval=zeros(2,9);
for i=1:9
[eval(:,i)]=solve(gamma/(R-(1+phi(1)*x)*(1+phi(2)))-z(i)-((1+alpha*beta)/beta*(gamma/x-y(i))), x);
end
Saying code is not that correct in Loop.
But, even after removing loop and plugging just y(1) and z(1) doesn't work.
Do you know the reason? Is it memory problem? or any suggestion, please?

It runs just fine for me if I remove the roundn call (as I don't have that function/toolbox/version).
Given your propensity to use builtin functions as variable names (beta, alpha, gamma, and eval), have you overwritten something else that is important (e.g., solve, syms, times).
