基于matlab的植物叶面积检测系统（suzy）(Matlab based on plant leaf area detection system (suzy))

说明：  椭圆滤波器具有很好的窄带滤波能力，比普通的FIR,IIR滤波器有更简单的结构(Elliptic filter has very good ability to narrow-band filter than the common FIR, IIR filters have a more simple structure)

多用户检测器的matlab仿真模型，欢迎下载。(Multi-user detector matlab simulation models are welcome to download.)

里面是论文，做毕业设计是能用到的，关于无线电损耗的(Which is the thesis, the final project is to be put to use, and on the radio loss)

音乐合成 内容：1) 自己朗诵一段文字，并录制成.wav 文件； 2) 利用 matlab，给这段录音添加背景音乐； 代码都嫁了注释(use matlab, add background music to the recording which you read a text )

模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。 (Simulated annealing algorithm derived from solid annealing principle, the solid is heated to a sufficiently high, let it cool slowly, when heated, solid particles with temperature becomes disordered state, the internal energy increases, while slowly cooling the particles gradually increasingly ordered at each temperature to reach equilibrium, and finally reach the ground state at normal temperature, which can be reduced to a minimum.)

说明：  使用FFT分析方波信号的频谱，讨论采样点数、采样频率对谱分辨率的影响。对数据叠加白噪声后再次分析实验结果。(Square-wave signal using the FFT spectrum analysis to discuss the sampling points, the sampling frequency of the impact of spectral resolution. White noise superimposed on the data after analysis of experimental results.)

此程序能将一个信号进行EMD分解，已近调试过，绝对没问题，主程序为emd1.m，用户可以随意更改里面的信号函数Xn。(This program converts a signal with EMD nearly debugged, absolutely no problem, main program for emd1.m, the user can freely change inside the signal function Xn.)

混沌图像加密，不错的界面程序，可以添加图片，非常实用(Chaotic image encryption, good interface program, you can add pictures, very practical)
