The MATLAB code which encrypt data based on AES technique.

frft的matlab实现，可以用于数字信号处理或图像加密(these programmes are matlab realization of frft that can be used in digital signal processing or image encryption)

This document is intended to serve as an introduction to Wavelet processing through a set of Matlab experiments. These experiments will gives an overview of three fundamental tasks in signal and image processing : signal, denoising and compression. These scripts are selfs contents (needed additional Matlab functions can be downloaded while reading the lectures). Each one of these five lectures should take between 1h and 2h in order to tests the various features of the scripts. One should copy/paste the provided code into a file names e.g. tp1.m, and launch the script directly from Matlab comand line > tp1 . Some of the scripts contains "holes" that you should try to fill on your own. I also provide the complete correction of these lectures as a set of Matlab scripts, but you should try as much as possible to avoid using them.

Base64编码说明 Base64编码要求把3个8位字节(3*8=24)转化为4个6位的字节(4*6=24),之后在6位的前面补两个0,形成8位一个字节的形式。 如果剩下的字符不...(Base64-encoded instructions require the Base64 encoding three 8-bit bytes (3* 8 = 24) was converted to 4 6 bytes (4* 6 = 24), then in front of the two s complement 6 0, 8 is formed bits in a byte form. If the rest of the characters do not ...)

说明：  这个程序是我自己编写的小车倒立摆经典PID控制和模糊控制matlab程序，相信对初学模糊控制的朋友有不小的帮助，包含传统PID控制和模糊控制的对比，是一份内容详细的完整报告(This program is written in my own car classic inverted pendulum PID control and fuzzy control matlab program, I believe beginner friends of fuzzy control no small help, with the traditional PID control and fuzzy control of contrast, is a complete and detailed report of)

在RGB、HSV、YCBCR空间提取得到了高质量的印章，算法鲁棒性很强。(the seal is well recognized in the space of RGB、HSV and YCBCR,and the method is robust.)

采用Matlab实现16QAM的调制与解调，要求画出星座图。(Matlab realize 16QAM modulation and demodulation, and asked to draw a constellation diagram.)

本书详细介绍了平时编程过程中可能范的各种错误，介绍了高质量C编程的各种知识以及各种技巧。(This book details the normal process of programming a variety of errors that might Fan introduced a variety of high-quality C programming knowledge and a variety of skills.)
