说明窗函数为文献窄时，STFT无频域的定位功能；(Note, when a narrow window function of literature, STFT-free frequency domain positioning function )

这是一本有关MATLAB的参考书，适合于使用MATLAB或正在打算使用MATLAB的读者 (This is a reference book for MATLAB, suitable for use with MATLAB or MATLAB is intended readers)

使用四分量高斯包络信号进行时频分析，比较比较STFT、WVD、CWD分辨率和交叉干扰情况，包含仿真代码及Matlab时频分析工具箱。工具箱的使用建议参考《Matlab时频分析技术及其应用-葛哲学》，压缩包中顺便包含了该书的源代码。(The four-component Gaussian envelope signal frequency analysis, comparison compare STFT on WVD, CWD resolution and cross-interference, frequency analysis toolbox contains the simulation code and Matlab. Use the recommended reference toolbox " Matlab frequency analysis technology and its application- Gezhe school" book contains the source code compression package the way.)

将K均值算法用于图像分割,输入的是彩色图像,转换为灰度图像进行分割,输出结果为灰度图像.利用灰度做为特征对每个像素进行聚类,由于光照等原因,有时应该属于一个物体的像素,其灰度值也会有很大的差别,可能导致对该像素的聚类发生错误.在分割结果中,该物体表面会出现一些不同于其它像素的噪声点,因此,算法的最后,对结果进行一次中值滤波,以消除噪声,达到平滑图像的作用(The K means algorithm for image segmentation, the input is a color image, convert to grayscale image segmentation, the output of grayscale images. The use of gray as the characteristics of each pixel clustering, due to light and other reasons, and sometimes should belong to an object pixel, its gray value will also be very different, may lead to clustering of the pixel error has occurred. in the segmentation results, the surface, there would be different from other pixel noise points, so , the algorithm Finally, the results of a median filter to eliminate noise, to the role of smoothing the image)

详细讲解了KALMAN 滤波的理论和KALMAN 滤波应用背景,讲的很详细,适合教学!(Explained in detail the theory and KALMAN KALMAN filter filtering application background, speak in great detail, suitable for teaching!)

风力机叶片最简化设计代码,只为提供一定的编程参考，具体说明代码内有详细备注，请多多指教(Most wind turbine blades to simplify the design code, only to provide a programming reference, specifying detailed notes in the code, the exhibitions)

Conceptually, a merge sort works as follows Divide the unsorted list into n sublists, each containing 1 element (a list of 1 element is considered sorted). Repeatedly merge sublists to produce new sorted sublists until there is only 1 sublist remaining. This will be the sorted list.

I found it s so terriable to search Fisher s exact test well written in matlab. So here is the file that produces p-value efficient, with good examples, easy for beginner s without any knowledge about theory behind.

This simulation file is in matlab software and is about the pwm closed loop chopper.
