Note that in your set up "while" loop, Z(i) can't be on both sides of the equal sign. Z(i) on the left side has to be Z(i+1).

There is nothing that terminates the execution of the loop when convergence is reached. Thus, the while-loop will run until the vector, Z, exceeds "Maximum possible array" or something else throws an error.
i=1;
Z(i)=1;
while true
Z(i+1) = 1 + B - q.*B.*(((Z(i))-B)./(((Z(i))-B*sigma)*((Z(i))+epsi*B)));
i = i+1;
end
Replace the loop by
tol = 1e-6;
i = 2;
Z(i) = 1;
Z(i-1) = Z(i)+2*tol;
while abs(Z(i)-Z(i-1)) >= tol
Z(i+1) = 1 + B - q.*B.*(((Z(i))-B)./(((Z(i))-B*sigma)*((Z(i))+epsi*B)));
i = i+1;
end

The purpose of
Z(i-1) = Z(i)+2*tol;
is to make sure that
abs(Z(i)-Z(i-1)) >= tol
returns true and thus that the statements in the while-loop are executed for i equal to 2. Try to execute the code without it.
