做信号处理的时候经常会用到FFT，而MATLAB自带的FFT只能变换出一列系数，想做成频谱图还要自己加一部分，自己写了一个小程序，输入原始信号和采样率，可以画出标准的幅值谱和功率谱。(Do signal processing is often used when the FFT, and FFT MATLAB own transformation from a coefficient of only wanted to make Canada part of the spectrum but also their own, to write a small program, the input original signal and the sampling rate can be Draw a standard amplitude spectrum and power spectrum.)

精细积分法用于结构动力学中，很好的方法，一般教材上没有(very important)

说明：  matlab实现HHT变换,包含具体EMD分解过程与信号重构过程(matlab EMD HHT, It includes specific EMD decomposition process and signal reconstruction process)

用来计算十字交叉点的中心位置,可以达到亚像素精度，在三维重建中经常会在物体表面做标志，本算法用于计算十字标记中心(to calculate the center of a cross image)

RSE (Regularized Selective Ensemble) is a selective ensemble learning algorithm for binay classification, which constructs ensemble under the regularization framework. In current version, the graph Laplacian serves as the regularizer, and unlabeled data can also be exploited to improve the performance.

MATLAB 球形摆控制源程序,实用广，可改用为其他程序控制(MATLAB ballbeam)

Blocking an image based on the specified window size.

说明：  根据最大相关性，最小冗余性的原则来优化特征空间结构(According to the principle of maximum correlation and minimum redundancy, the feature space structure is optimized)

精通matlab6.5,向读者提供色彩信息、动态交互的软件环境，提供读者实践本书内容所需的各种文件。(Is proficient matlab6.5, to provide color information to the reader, dynamic interactive software environment, providing the reader practice the book the various documents required.)

说明：  基于PWM控制的无刷直流仿真，实验结果良好，具有很好的参考价值。(Based on the PWM control of Brushless DC simulation, the experimental results are good, has a good reference value.)
