Using different names for functions that do the same thing

国密算法4的实现方法，有源代码。可借用。sm4可以用软件方法实现。也可用硬件方法实现。国密4是对称算法的一种。 和 des  3des算法相似。 方法简单易懂。

stm32f4xx的工程模板，适用于stm32f407vet6,stm32f407zet6,stm32f407zgt6等(Stm32f4xx engineering template, suitable for stm32f407vet6, stm32f407zet6, stm32f407zgt6, etc.)

vc和mat混合编程，利用matlab的com组件来实现mat和vc的混合编程(vc and mat mixed programming, the use of matlab' s com vc components to achieve mat and Hybrid Programming)

你的师傅就大方的功夫会返回家公司的风格是大方和高度是刚好是(Your master the generous effort will return to the style of the company is generous, and the height is just)

C51 编译用头文件，可以用于C51 开发，对于不同C51定义不同： /// Used with pointers, declares a generic pointer.  Generic pointers /// work with any memory space but are inefficient. #define SEG_GENERIC /// Declares a variable to be located in 8051 DATA space. #define SEG_DATA data /// Declares a variable to be located in 8051 IDATA space. #define SEG_IDATA idata /// Declares a variable to be located in 8051 XDATA space. #define SEG_XDATA xdata /// Declares a variable to be located in 8051 PDATA space. #define SEG_PDATA pdata /// Declares a variable to be located in 8051 BDATA (bit-addressable) space. #define SEG_BDATA bdata /// Declares a variable to be located in 8051 CODE space. #define SEG_CODE code

本文件包含7章理论学习和4章手动实验，内容涉及SPI协议，动态扫描，串口传输，电机控制等(This document contains 7 chapters of theoretical learning and 4 chapter manual experiments, involving SPI protocol, dynamic scanning, serial port transmission, motor control and so on.)

fuzzy ahp,即模糊层次分析法的原始程序，该程序实现了输入模糊数输出相对权重的功能，可以被很好使用(fuzzy ahp, FAHP the original procedure, the program input output fuzzy numbers relative weighting function can be well used)

脉宽调制，亲自调试通过，是一个很好学习的资料(Pulse width modulation, self-testing, is a very good learning material.)

利用哈希运算产生服务端和客户端的通信密钥( Produces the service end and the customer end correspondence key using the Hasche operation )

说明：  实现角度向弧度的转换，并判断所属象限。。。(Realize the conversion of angle to radian, and judge the quadrant.)
