The solution (that is, <math>V_{out}</math>) is found by first iterating as described above to find the transistor operating points to the desired precision, then solving under AC conditions to find the correct <math>V_{out}</math>. "Solving" (both during iteration and for the final answer) involves running the 24-equation matrix through MATLAB and selecting out the solution generated for the <math>V_{out}</math> variable.
