Simulation for DC Motor selection. It includes two files, which are DCMotor_Trj.m and DCMotor.mdl. First of all, you run the DCMotor_Trj.m for generating the reference trajectory. Then, you open the Simulink file(DCMotor.mdl) and run! You may change DC Motor parameters.

此代码为较为全面的ofdm无线通信的链路仿真，实现了信道模型，传输等，内容翔实，适合无线通信专业的研究生学习。(This code is more comprehensive wireless communications link ofdm simulation to achieve a channel model, transmission, informative, suitable for wireless communications professional graduate study.)

计算无线衰落信道平均时延扩展和均方根时延扩展(delay spread and square delay spread calculation code)

用于产生杂波的simulink模块，已经过验证，好用(For generating a clutter Simulink module, has already been verified, good use)

设计了巴特沃斯、车比雪夫I，Ⅱ型、椭圆滤波器，并有对心电信号的低通处理。(Designed Butterworth, Chebyshev car I, Ⅱ type, Elliptic filters, as well as on the ECG of the low-pass deal.)

matlab图像处理，把初始图像处理后，进行水印提取(matlab)

最好的MATLAB书，即可以作入门教材，又可以做实用手册。买的话贵了一点，现在出了7.0版，但是还是这本6.5版经典。个人认为最先出的书是有真知灼见的作者写的，后来的都是抄别人的。(the best book that can make introductory materials, can do practical manual. Buy the expensive, but now a version 7.0, or 6.5 version of this classic. Personally think that the first book is a vision of the author, were later copied by others.)

matlab实现用双线性插值法放大和缩小图像(Zooming and Shrinking Images by Bilinear Interpolation (a) Write a computer program capable of zooming and shrinking an image by bilinear interpolation. The input to your program is the desired size of the resulting image in the horizontal and vertical direction. You may ignore aliasing effects. (b) Download Fig. 2.19(a) and use your program to shrink this image 1024 x 1024 to 256 x 256 pixels. (c) Use your program to zoom the image in (b) back to 1024 x 1024. Explain the reasons for their differences. )
