很有用的源代码，实现的效果很好，很值得收藏，不错平(Useful source code, to achieve good results, it is worth collecting, good level)

选择两张图片，一张水印图，一张嵌入图，将水印图进行Arnold置乱算法将其置乱，嵌入到嵌入图中，形成数字零水印，选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded map to form digital zero watermark. We choose white noise, Gauss low pass filtering, compression, shearing and rotation attack test. To observe the robustness of the image)

火箭尾喷管的设计，主要包括动力计算，外形轮廓计算，温度计算及激波分布等。使用matlab编写(Rocket nozzle design)

Matlab中几个经典的编程例子，很适合初学者(Matlab, the programming of several classic examples, it is suitable for beginners)

本程序是关于fdtd磁场计算相关的，经过调试成功，希望大家多多参考并提建议(pmlfdtd)

这个程序是基于matlab的计算工件粗糙度的轮廓算术平均偏差Ra的值。里面有例程，还有详细的代码注释，希望对各位有所帮助，代码段还有不完善的地方，运行时间过长，会报错，但是逻辑是没有问题的，日后再改进大家可以基于此来书写新的程序，算是抛砖引玉吧(This procedure is based on the calculation of the value of matlab workpiece contour arithmetic average roughness Ra of deviation. There are routines, as well as detailed code comments, you would like to help, there are imperfections in the code segment, at a later improvement, but logic should be no problem, we can be written based on this new program, regarded puts it)

A function that performs mvdr beamforming on every frequency in a source estimation where the doa is known.

说明：  对信号处理的理论知识作系统概括和总结的基础上，介绍了如何使用matlab提供的信号处理工具箱，(Of theoretical knowledge of signal processing systems in general and for the basis of summing up on how to use matlab to provide the signal processing toolbox)

说明：  单极型倍频SPWM simulink仿真，和同等单极性SPWM相比，相同的开关频率，输出电压THD更低，逆变器输出可使用更小的滤波器，对逆变器体积的降低很有帮助，封装子系统，调制度、载波比和调制频率可自由调节，简单易用。matlab版本：2015b(Compared with the same unipolar SPWM, the same switching frequency and output voltage thd are lower. The output of the inverter can use smaller filters, which is very helpful to reduce the volume of the inverter. The package subsystem, modulation system, carrier ratio and modulation frequency rate can be adjusted freely and easy to use. Matlab version: 2015b)
