数值分析课程设计，内附MATLAB源码和word,用三次样条插值设计中英文签名，双三次做改进； 采用交互式界面进行操作，用鼠标点击获取名字大致的数据点 三次样条插值算法：可产生二阶光滑度，即二阶导数连续签名图样(Numerical analysis of curriculum design, enclosing the MATLAB source code and the word, using cubic spline interpolation design in English and Chinese signatures, double the three to do to improve using an interactive interface to operate with a mouse click to obtain the name of the data points roughly cubic spline interpolation algorithm: can generate second-order smoothness, that is, a continuous second derivative sign pattern)

系统辨识里面的梯度校正参数辨识方法，实用的系统辨识算法(System identification inside the gradient correction parameter identification methods, practical system identification algorithm)

集中了大部分matlab基础经典程序 1-32是：图形应用篇 33-66是：界面设计篇 67-84是：图形处理篇 85-100是：数值分析篇(Matlab concentrate most of the procedures based on the classic 1-32 is: graphics application papers 33-66 are: interface design papers 67-84 are: graphics processing chapter 85-100 is: Numerical Analysis Section)

三电平逆变器，可以帮助读者完成仿真任务，更方便的得到仿真波形(Three-level inverter, you can help the reader to complete the simulation tasks, and more convenient to get the simulation waveforms)

采用快速傅里叶变化，进而获得函数的相频特性和幅频特性(Phase frequency characteristics amplitude-frequency characteristics using the fast Fourier transform, and then get the function)

k means techniques de classification non supervisée (clustering) les plus utilisées. Etant donné un entier K, K-means partitionne les données en K groupes, ou "clusters", ou "classes" ne se chevauchant pas. Ce résultat est obtenu en positionnant K "prototypes", ou "centroï des" dans les régions de l espace les plus peuplées. Chaque observation est alors affectée au prototype le plus proche (règle dite "de la Distance Minimale"). Chaque classe contient donc les observations qui sont plus proches d un certain prototype que de tout autre prototype

ofdm的仿真程序，可以直接运行，希望对大家有所帮助！(ofdm simulation program can be run directly, we want to help!)

说明：  极坐标牛拉法和PQ分解法计算IEEE14节点(Calculation of IEEE14 nodes by polar coordinate niula method and PQ decomposition method)

给定栅格图象及其变形后的栅格图象，请你首先确定各栅格交叉点的位移，然后采用控制栅格的方法编写实现图象几何校正的程序。 (A given image and deformed grid of the raster image, you first determine the grid cross-point displacement, and then the methods used to control the preparation of the realization of raster image geometric correction procedure.)
