功率谱估计 信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Power spectrum estimation signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signal are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. Is the sampling frequency. Levinson recursive method were used and Burg method for power spectrum estimation, and change the length of the data analysis, the impact on the estimation model order spectrum.)

我们上课用的MATLAB课件，课件不错，就是老师讲的比较差劲。(the ppt of matlab used in my class)

利用DCT进行图像压缩（首先将图像分割成8×8的图像，对每个子图像进行DCT，这样每个子图像有64个系数，舍去50％小的变换系数，进行2：1的压缩。）(Using DCT for image compression (first image into 8 × 8 image, for each sub-image DCT, so that each sub-image by a factor of 64, rounding 50 of the small transform coefficients, the 2:1 compression.))

基于Harris原理的亚像素角点坐标检测Matlab程序；直接运行click_calib .m文件即可获得亚像素级角点坐标，附录Ⅱ中的其它函数文件均会被click_calib .m文件调用。(Based on the principle of subpixel Harris corner coordinates detection Matlab procedures run directly click_calib. M file to obtain sub-pixel corner coordinates, Appendix Ⅱ other functions in the file will be click_calib. M file called.)

应用matlab实现了二维的有限差分正演，是实现地球物理正演模拟方法的基础。(Applied to achieve a two-dimensional matlab finite difference forward, is to achieve geophysical forward modeling approach is based on.)

it includes pattern recognition tools for matlab software

数据仓库中，数据挖掘的一个程序，用MATLAB编写，好用！(Data warehouse, data mining, a procedure, using MATLAB to prepare, easy to use!)

DOA估计中的基本music算法，一个是有问题的，另一个是针对前一个的改进，有重大学习意义(DOA estimates of basic music algorithm is a problem, the other is aimed at improving the one before, meaning a major study)

简述了雷达微波目标模拟器的组成、工作原理以及用途。该目标模拟器已成功地用于跟踪雷达,达到了预期的性能。 (Briefly the composition of works and use of the microwave radar target simulator. The target simulator has been used successfully tracking radar, to achieve the desired performance.)
