本書是Brian W. Kernighan和Rob Pike合著的最新力作。本書從排錯、測試、性能、可移植性、設計、界面、風格和記法等方面，討論了程序設計中實際的、又是非常深刻和具有廣泛意義的思想、技術和方法，它的翻譯出版將填補國內目前這方面書籍的空白。本書值得每個夢想并努力使自己成為優秀程序員的人參考，值得每個計算機專業的學生和計算機工作者閱讀，也可作為程序設計高級課程的教材或參考書。
Returns weighted percentiles of a sample given the weight vector w
％ The idea is to give more emphasis in some examples of data as compared to
％ others by giving more weight. For example, we could give lower weights to
％ the outliers.
％ The motivation to write this function is to compute percentiles for Monte
％ Carlos simulations where some simulations are very bad (in terms of goodness
％ of fit between simulated and actual value) than the others and to give
％ the lower weights based on some goodness of fit criteria.
I wrote this code early this year using ColdFire MCF5213 in codewarrior IDE. The LCD is STN B/W 320x240 dot matrix LCD. The code include 3 different fonts, and basic LCD driver. All original!
