数字调制信号与仿真的书本中的第四章节的MATLAB仿真代码，需要的话可以跟我联系取得其他章节的代码(And simulation of digital modulation signals in the fourth chapter of the book MATLAB simulation code, you need to contact me if you can obtain the other chapters of the code)

说明：  这是个关于图像大津法分割算法的源程序，在matlab上实现。(This is about image segmentation algorithm of Otsu' s source code, in matlab to achieve.)

迭代法求最佳阈值 图像为baboon.bmp 分别对R,G,B三个颜色求阈值，进行分割(Iterative method for the optimal threshold image baboon.bmp respectively R, G, B three colors for the threshold segmentation)

这是一本很少见的中文matlab帮助手册，特别对于点运算等入门级知识进行了详解，大家共享吧！(This is a very rare Chinese matlab help manual, particularly for entry-level point of computing, such as the detailed knowledge, share it!)

Here s the code! Too many people ask for this Using this code you can save an image item as a jpeg image, specifying the quality of it. Jpeg quality is the same as compression so the lower the quality, the smaller the file size. It s simple to use(Here's the code! Too many people ask for this Using this code you can save an image item as a jpe g image, specifying the quality of it. Jpeg quality is th e same as compression so the lower the quality, the smaller the file size. It's simple to use)

将Quaternion四元素坐标系转换为一般的欧拉角坐标系，避免采用反三角函数导致的值域限制问题。参数xi为搜索的精度，对于每个欧拉角可以分别设定，xi越小，搜索越精确。(Quaternion quaternion coordinate system will be converted to general Euler angle coordinate system, avoiding the use of inverse trigonometric functions due to range limitations. The accuracy of the search parameter xi, for each Euler angle can be set separately, xi smaller, more accurate search.)

MPU6050陀螺仪，代码，技术文档， 测试程序(MPU6050 gyroscope, code, technical documentation, test programs)

simulink双效串并联吸收式制冷动态仿真(simulation for absorption refrigeration)

采用极大似然估计辨识方法，对系统参数进行辨识。(The maximum likelihood estimation method is used to identify the system parameters.)

本程序是基于DCT的数字水印算法，包含水印的嵌入，提取过程！(watermarking scheme based on DCT！)
