《极品列车时刻表》- Need for Train Timetable

说明：  实现了算法优先分析的功能，可当作编译原理实验报告使用。压缩包内具有完整的实验报告(It realizes the function of priority analysis of algorithm and can be used as compiler principle experiment report. Compressed package with complete experimental report)

说明：  对中海庭给的高精地图数据进行清洗，简易代码(data processing of HD map data)

doc x sr04

说明：  神经网络与深度学习课后习题代码，编程案列(Neural Network and Deep Learning Exercise Code, Programming List)

两点边值问题的打靶法,也是自己亲手做的一个作业(Boundary Value Problems shooting method, also by myself)

VB通过注册表禁用Windows某些桌面属性，具体到本例来说，是通过修改注册表禁止用户通过桌面右键来打开桌面属性选项，从而禁用了系统属性功能，这只是一个VB修改注册表的实例，禁用桌面属性只是一个功能演示。

利用grads计算ncep-fnl资料的的水汽通量及水汽通量散度(The calculation of water vapor flux and water flux divergence about the ncep- FNL data by using grads)

说明：  精子的分布具有不均匀性，其分布毫无规律，十分散乱，精子的游动方向各不相同，其尾部有的张开，也有的和头部重合，且背景以灰色为主，还有白色等混杂的颜色。本题要求在这样混杂的二十五张图片中求出每张图内所含的精子数目。(The distribution of sperm is not uniform, its distribution is irregular, very scattered, the swimming direction of sperm is different, some of its tail is open, some coincide with the head, and the background is mainly gray, there are mixed colors such as white. In this question, we need to find out the number of sperm in each of the 25 mixed pictures.)

说明：  使用matlab实现逻辑回归实现二分类问题，并加入了交叉验证的程序，提高分类准确性(Matlab is used to realize the binary classification problem,and the cross validation program is added to improve the accuracy of classification)
