这是用matlab编写的100个小程序，以供大家参考学习。(this is an usefull materials,it is helpful for matlab learner)

使用MATLAB软件编写程序，然后进行仿真，最后生成图像(Programming using MATLAB software, and then simulated to generate the final image)

魔术公式轮胎模型，不同侧偏刚度，不同纵向滑移率下的轮胎纵横向力出图，m文件编写，可直接运行。(magic tire model. matlab/simulink m. coordinate model. magic tire model. matlab/simulink m. coordinate model)

考虑频率偏移的OFDM仿真程序,直接根据经典参考文献编写(Consider the frequency offset of OFDM simulation program, directly from the classic reference preparation)

支持向量机用matlab来实现，能够实现简单的图像功能，还能让人深刻理解向量机思想(Support vector machine matlab to achieve, to achieve simple image function, but also a deep understanding of people thinking vector machine)

说明：  本文提出了一种基于混沌加密的DCT域二值图像数字水印算法.该算法首先利用混沌序列将含有版权信息的有意义二值图像水印进行加密,然后利用人眼视觉系统(HVS)的特性将原始载体图像进行块分类,最后将不同强度的水印分量嵌入到不同类的图像块DCT中频系数中去.利用混沌序列对水印进行加密,使水印本身具有安全性,对数字作品进行双重保障.通过高斯噪声,椒盐噪声以及JPEG压缩和剪切等攻击试验,表明了该算法具有较好的鲁棒性.(Encryption in DCT domain is proposed. Firstly, the meaningful binary image watermark containing copyright information is encrypted by using chaotic sequence, and then the original image is classified by using the characteristics of human visual system (HVS), Finally, the watermark components with different intensities are embedded into the DCT intermediate frequency coefficients of different types of image blocks. Chaotic sequences are used to encrypt the watermark, so that the watermark itself has security and double protection for digital works. Experiments on Gaussian noise, salt and pepper noise, JPEG compression and clipping show that the algorithm has good robustness)
