Iterative Methods
Coordinate operation calculations can almost always be formulated using an iterative method
Advantages:
- Object Reference Model parameters embedded as variables.
- If properly formulated they are almost always more efficient for the same accuracy as a power series.
- Usually the expressions involved are compact.
Disadvantages:
- Convergence rate depends on formulation and quality of the initial value.
- Initial guess must be efficient to compute.
- Efficient-to-compute stopping criterion is needed
- Even when this approach works, the direct approximation is almost always more efficient.
