What is 'In' and What is 'Out' in EngineeringProblem Solving

摘要

The introduction of mathematical software packages as effective and efficient means forengineering problem solving allows the retirement of many calculational methods andthe application of efficient computer-based techniques that are enabled by effectivesoftware. This paper discusses the following issues: analytical versus numerical solutiontechniques, graphical versus numerical solution techniques, teaching numerical methodsand programming, validation and comparison of regression models, and determinationof the number of significant digits in the reported results of numerical solutions.
