It is a matlab code for K Nearest Neighbor algorithm.

在风力发电的模拟控制系统中,风速的模拟是一个重要的环节,而正确的风速模型不仅能够很好的 反应实际风速变化情况,而且能够给风力发电系统研究提供正确的源参数。本文用 Matlab/Simulink建立了风速组合数学模型,该模型将风速分为基本风速、阵风、渐变风速和组合风速4部分,仿真结果表明该模型能够理想的反应实际风速。(In the simulation control system of wind power generation, wind speed simulation is an important link, and the correct wind speed model can not only reflect the actual wind speed changes, but also provide the correct source parameters for wind power system research. In this paper, a combined mathematical model of wind speed is established by using MATLAB / Simulink. The model divides the wind speed into four parts: basic wind speed, gust wind, gradual wind speed and combined wind speed. The simulation results show that the model can reflect the actual wind speed perfectly.)

有记忆HPA的建模！am/am以及am/pm特性曲线！采用经典的saleh模型！(Modeling of HPA with memory! am/am and am/pm curve! Saleh model using classic!)

用基于 Matlab 的小容量 FFT (比如 256×256)程序，将取样窗口划分为 若干个全等的小矩形,对每个小矩形内离散点的复振幅作 FFT 变换,然后将所有变 换结果叠加，再乘以复数相位因子,相当于对整个物面上点进行菲涅耳衍射计算， 利用这种方法可以迅速的实现高精度的轴对称傍轴光学系统中的激光衍射计算 (With a small volume based on Matlab FFT (eg 256 × 256) procedure to sample window divided into a number of small identical rectangles, each small rectangle of discrete points within the complex amplitude for the FFT transform, and then transform the results of all the superposition multiplied by the complex phase factor, the equivalent point on the object plane Fresnel diffraction calculation, the use of this method can rapidly achieve high-precision optical system axis of symmetry in the paraxial calculation of laser diffraction)
