Condition number of system of non-linear equations. The system has only two unknowns but 6 equations (thus over-determined). Solving the system of equations are not a problem. However, I need an indication of how well-conditioned the system of equations is. I know the condition number is typically used to do this. Any advice on exactly how this procedure works will be appreciated.
Answer & Explanation
Let say that you have equations for unknowns (). You can consider minimizing of the norm
hoping that at solution will be zero. The Jacobian of the system leads to a square system.
