说明：  通过不同大小的窗口移动，计算每个窗口内地形剖面数据的均方根值，得到的数据在双对数图中拟合直线可求得分维数(move the windows of different size and calculate the rms of the data in the window.Then using the resultant data to plot,so that the fractal dimension can be gotten.)

这是一个低通抽样定理，例题中包括了低通信号的波形，抽样速率为4Hz的抽样信号，抽样序列恢复出原始信号(This is a low-pass sampling theorem, examples included in the lowpass signal waveform, the sampling rate is 4Hz sampling signal to recover the original signal sample sequence)

对正选信号进行仿真，画频谱图，并分别在时域和频域对信号延迟。(Positive selection signal delay simulation)

一个matlab编写的封闭边界油藏单相流体定产量生产的数值模拟程序，对学习油藏数值模拟有很大的帮助和引导作用(Matlab prepared a closed boundary reservoir volume production of single-phase fluid given numerical simulation, reservoir simulation study of great help and guide)

利用小波变换进行通信信道自试验均衡，介绍了算法设计理论并给出了算法详细描述及实验结果。(Wavelet transform from the test communication channel equalization, introduced the theory of algorithm design and gives a detailed description of the algorithm and experimental results.)

产生了PN序列，并通过仿真检测了他的自相关特性。(generate the PN sequency an simulate the auto-correlation property.)

很强的matlab程序，有很大的学习价值，里面不仅有详细的介绍，以及规范的书写(Matlab program strong, have great learning value, which is not only a detailed description, and specification writing)

matlab的.m文件，对影像计算不同方向的经验半方差,检测某区域的空间异质性(matlab' s. m files, image computing experience of semi-variance in different directions to detect spatial heterogeneity of a region)

该程序用以对2FSK信号调制解调的仿真程序，信道为高斯白噪声，采用FFT方法对其解调(procedures for the right 2FSK signal modulation and demodulation of the simulation program, channel for white Gaussian noise, FFT method demodulation)
