说明：  求解分形维数，采用功能函数法，很方便，从而很好的对分形几何进行分析(Solving the fractal dimension, function by function, it is convenient to a good analysis of fractal geometry)

初学入门教程，学会用matlab gui设计用户界面，并编写响应程序。(Beginners Tutorial, learn how to use matlab gui user interface design, and write response procedures.)

是两质量系统matlab中simulink模型(Two quality system matlab simulink model)

谐波治理检测和分析的Matlab程序，含部分注释及结果图示(Harmonic detection and analysis of Matlab procedures, including some comments and the results shown)

用于信号处理的MATLAB基本操作，离散时间的信号，典型序列(MATLAB for the basic operation of signal processing, discrete-time signal, a typical sequence)

基于boundar边界提取轮廓，采用曲率算法确定可能为指尖或者指根点的区域，采用该程序确定指尖指根区域。(Contour extraction based on boundar border, using the curvature method to determine the root may refer to point fingers or regions that use the procedure to determine the root area fingertips.)

进行OFDM系统的matlab仿真，其中采用的子载波数为8个。并且仿真了多普勒频移对OFDM的影响。基带调制采用QPSK(Matlab simulation for OFDM system, which USES the subcarrier number is eight.And simulation of the doppler shift effect on OFDM.Baseband using QPSK modulation)

是对于是128*128灰度图片的压缩MATLAB代码,希望有人会有用(For 28* 123 gray image compression MATLAB code, hope someone will be useful for)

计算图像PSNR，非常高效的源码，具有一定的参考价值。(Calculated image PSNR, very efficient source, with some reference value.)
