c语言的main函数到底怎么写的
前言
main函数是程序启动后执行的第一个函数。从开始学习C语言到现在，我们似乎看到了很多个版本的main函数，那么哪一种才是正确的呢？我们先来看看目前有哪些版本。
main函数版本
第一种，没有返回值，没有入参：
main()
在C89标准中，这种写法是可以接受的，但使用现在的编译器编译时，会报告警，并且会将其返回值默认为int。实际上，如果函数没有显式声明返回类型，那么编译...
Linux常用命令-文本查看篇
前言
Linux常用命令中，除了cat还有很多其他用于文本查看的命令。本文将简单介绍一下这些文本查看的命令。
全文本显示--cat
cat可能是常用的一个文本查看命令了，使用方法也很简单：
cat file #全文本显示在终端
cat -n file #显示全文本，并显示行号
另外，cat也可用作合并文件：
cat file1 file2 >file3
该命令将fil...

高斯滤波(仅满足学习需求）
大三上学期，数字摄影测量（张云生教授）一课中第一个实验：高斯滤波
以下主要是本人在该实验过程中发现的问题，仅作为日后参考
问题：
input()函数默认输入的为字符型
计算n的m次幂时尽量使用：n**m
尽量不要使用循环，会使程序变慢
缩进是python的灵魂
@jit 仅仅作为尝试，并未掌握
疑问：
python允许不声明（或使用前声明）变量而直接使用，但在矩阵时就出现了问题

【图像处理】透视变换 Perspective Transformation（小细节修正和推导流程补充）
这部分的推导，首先是求解∆x3，∆y3,然后通过得到的方程组，求解可得a13，a23,然后通过∆x1，∆x2分别求得a21，a11，同样的通过∆y1，∆y2求得a22和a12，至此透视变换矩阵所有元素求解完毕。 类似地，首先是求解∆x3，∆y3,然后通过得到的方程组，求解可得a13，a23,然后通过x3-x0，x1-x0分别求得a21，a11，同样的通过y3-y0，y1-y0求得a22和a12，至此同样的透视变换矩阵所有元素求解完毕。 具体代码实现，请参考原博文：https://blog.cs

有关POE及POE+以太网供电系统标准IEEE802.3af与at的区别解析
IEEE 802.3af和IEEE 802.3AT标准都是通过以太网数据线对或备用线对来实现以太网设备供电，它们突破了以太网的应用，而它们主要是一个电源传输协议，不是数据协议。
IEEE 协会于2003年6月批准了802. 3af 标准，它明确规定了远程系统中的电力检测和控制事项，并对路由器、交换机和集线器通过以太网电缆向IP电话、安全系统以及无线LAN 接入点等设备供电的方式进行了规定。
