本書(shū)是Brian W. Kernighan和Rob Pike合著的最新力作。本書(shū)從排錯(cuò)、測(cè)試、性能、可移植性、設(shè)計(jì)、界面、風(fēng)格和記法等方面，討論了程序設(shè)計(jì)中實(shí)際的、又是非常深刻和具有廣泛意義的思想、技術(shù)和方法，它的翻譯出版將填補(bǔ)國(guó)內(nèi)目前這方面書(shū)籍的空白。本書(shū)值得每個(gè)夢(mèng)想并努力使自己成為優(yōu)秀程序員的人參考，值得每個(gè)計(jì)算機(jī)專(zhuān)業(yè)的學(xué)生和計(jì)算機(jī)工作者閱讀，也可作為程序設(shè)計(jì)高級(jí)課程的教材或參考書(shū)。
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.
