Summary
This chapter has described numerous things that can go wrong when
performing numerical computations. You won’t encounter most of these
difficulties when you solve practical lower-order problems. The problems
described here pertain to all computer analysis packages. MATLAB has some
of the best algorithms available, and, where possible, notifies you when there
are difficulties. The important points to remember are:
•State-space models are, in general, the most reliable models for subsequent
computations.
•Scaling model data can improve the accuracy of your results.
•Numerical computing is a tricky business, and virtually all computer tools
can fail under certain conditions.
