| 中文摘要 | 經過電算機處理後,由於處理誤差常使最終所產生的一串數字已看不出意義了。處理誤差幾乎無法控制。只有借擴張資料位元;或使用階乘數字系統以改善誤差。另一方面,符號程式已經發展有二十年之久。它的優點已眾所周知,但是它進步很少。目前仍無法對處理誤差有所幫助。筆者認為能減少誤差的是:中間處理的約減,算術過程中符號的吸收,極-零點的對消,及工具函數的使用。 在本文中,作者強調工具函數的重要性;並推展它的應用至拉氏分析。本文所用的工具函數為泰勒及勞倫級數。目前作者仍在努力找尋更有效的工具函數中。 |
| 英文摘要 | Owing to the error of computing process, the process of a digital computer of numerical numbers will eventually produce a series of meaningless numbers. The error produced can be controlled by no means but by expansion of data bytes or possibly by the factorial number system. On the other hand, symbolic programming has been proposed for more than 2-decade. Its benefits are well known; but it advances very little and hardly helps to reduce profess error. The author realizes that those that will benefit accuracy are reductions of intermediate processes, symbolic absorptions in the arithmetical operations, pole-zero cancellations, and use of proper 'tool functioin'. In this article, the author means to emphasize the importance of the 'tool function' and to expand its application area to over the Laplace analysis as well. The tool function in this article is a Taylor and a Laurent series. The auther is stillstriving to find a more powerful tool function. |
