关于rfid射频技术的实现方式的软件研究，并通过matlab进行了仿真(Theory of rfid programming，similation in matlab environment)

matlab 数据采集 小车轨迹 串口 绘图(Matlab Data Acquisition car track serial drawing)

利用此程序，可以对图片的边缘特征进行提取，进而进行图片的分类，并统计出分类的正确率。(With this program, you can picture the edge feature extraction, and then classify pictures and statistics of the correct rate of classification.)

ES is a symmetric block cipher. The same key is used to encrypt and decrypt the message. The plain text and the cipher text are the same size. The Aes algorithm works as follows: Convert to state array: This step consists of conversion on the matrix onto a state array operating with the sbox. Transformations (and their inverses) AddRoundKey: Computing the round key for each round. SubBytes: Substituting by bytes from Sbox. ShiftRows: Shifting of rows. MixColumns: Exor operation on columns. Key Expansion: Expanding the key to be used on next round.
