5扩32 扩频方法仿真 进行SNR估计 产生pn码 基带仿真(5 extended to 32 spread-spectrum method is estimated SNR simulation)

matlab做的图像检索文档。里面3组图片可以试一试。(Matlab to do image retrieval. In 3group of pictures can try.)

vc和matlab的混合编程，很好很全的(vc and matlab programming mix, full of very good)

1SpectralClustering_V1_1 Algorithm

说明：  通过时域转换为频域，在频域中截取低频部分，去掉高频部分将结果再转换到时域以实现低通滤波的功能。(Through the time domain is converted to frequency domain, in the frequency domain low-frequency part of the interception, to remove high-frequency part of the results and then switch to the time domain in order to achieve low-pass filter function.)

对莫尔斯码的仿真实现，个人感觉比较简单。体现出了莫尔斯码1：3的点划比例，需要的人可以参考一下(Morse code simulation to achieve personal feeling is relatively simple. Reflect the point of Morse code 1:3 draw ratio of those who need it can reference)

北京航空航天大学出版社的matlab从零进阶第四章节的小程序(Matlab Beijing University of Aeronautics and Astronautics Press from zero advanced fourth chapter applet)

基于simulink powersystem元件库提供的光伏电池模型建立了扰动观测法的最大功率跟踪控制模型（MPPT），仿真模型能够很好的追踪最大功率点(Based on the photovoltaic cell model provided by Simulink powersystem component library, the maximum power tracking control model (MPPT) of disturbance observation method is established. The simulation model can well track the maximum power point)

说明：  abaqus金属材料子程序开发语句说明，有助于读者理解编程含义。(Description of ABAQUS subroutine for metal materials)

matlab dsp(1． 利用自相关函数法和周期图法实现随机信号的功率谱估计。 2． 观察数据长度、自相关序列长度、信噪比、窗函数、平均次数等对谱估计的分辨率、稳定性、主瓣宽度和旁瓣效应的影响
