超级好用的书，面试必备，包括常用的算法介绍，面试题目等等(Super easy to book, interview essential, including the commonly used algorithm is introduced, interview questions, etc.)

基于贝叶斯-KNN文本分类算法的设计与实现。 是贝叶斯和ＫＮＮ两种分类算法的结合。(Bayesian-KNN text categorization algorithm design and implementation. Bayes and KNN is a combination of two kinds of classification algorithms.)

本程序针对内弹道的计算实现火炮内弹道计算(The procedure for the calculation of the interior ballistics Gun Interior Ballistic calculation)

主要是交通行业的时空矩阵的3维热力图表达方式，不同检测器与不同时间段的流量作为颜色的第三位导入，热力图调整颜色表达更清晰(mianly used for transportation engineering. It can plot the three dimension of the real traffic situation, including different temporal and spatial. the code also can modify the parameter of the colorbar.)

说明：  Umat Abaqus for plasticity

说明：  牛顿法又称牛顿-拉弗森方法（Newton-Raphson method），是一种在实数域和复数域上近似求解方程的方法。本程序收敛速度快，迭代步数可取大一些(Newton method, also known as Newton-Raphson method, is an approximate method for solving equations in real and complex fields. The program has fast convergence speed so the number of iteration steps can be larger.)
