256色转灰度图，用matlab实现一副彩色图像的灰度变换，但必须是bmp格式的图像(256-color to grayscale, using matlab to achieve a color image of the gray-scale transformation, but it must be bmp format images)

When capturing an iris image under unconstrained conditions and without user cooperation, the image quality can be highly degraded by poor focus, off-angle view, motion blur, specular reflection (SR), and other artifacts. The noisy iris images increase the intra-individual variations, thus markedly degrading recognition accuracy. To overcome these problems, we propose a new iris recognition algorithm for noisy iris images.

实现一个单相不控的全桥整流器 交流母线电阻R1，直流滤波电容C，负载电阻R(achieve a single-phase control is not a full-bridge rectifier AC Bus resistor R1, DC filtering capacitor C, load resistor R)

Image compression using SVD is a very useful compression algorithm. The image size will not decrease in the compression algorithm.

Tests hypothesis that 2 variables are equally correlated with a 3rd if values from all 3 are paired

useful for students to learn leach algorithm using matlab for wireless sensor network

利用Peng_Robinson EOS 计算常见纯组分气体逸度和密度。利用matlab运行求解。(Peng Robinson is used to calculate the density and fugacity of single component gas at given pressure with Peng-Robinson equation.)

some code in matlab programming on NSGA. the code is complete and written using cvx tools. enjoy

图像处理中经典的PCA算法，几乎每一步的降维之前都要用到 实用性很强(PCA classical image processing algorithms, almost every step of dimension reduction should be used in very practical before)

在保密数据传递等应用中，有时采用将一句话或一段文字或一段音乐隐藏在另一段音乐中，然后利用专门的算法来提取所传的信息(Data transfer in applications such as security, sometimes using the word or a text or a piece of music hidden in another section of music, and then use a special algorithm to extract the information transmission)
