说明：  利用QR算法解household变换阵，用Householder变换法对矩阵A作正交分解(QR Algorithm for household use transformation matrix)

说明：  这个是一个关于ofdm的程序，里面有很重要的东西，希望大家多看看！(This is a study on the OFDM procedures, there are very important things, I hope we see more!)

说明：  在matlab环境下编写的完整程序。其中包含DA AD 转换(Written in the matlab environment, the full program. Which contains the DA AD conversion)

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)

1、基于Ip/Iq方法控制PWM整流器，实现有功无功解耦控制，实现直流电容的稳压控制。 2、分别采用滞环电流和电压空间矢量技术进行PWM调制 3、DSTATCOM无功补偿仿真验证 4、系统采用了在带有前馈解耦控制的基础上产生的电压电流双闭环控制结构，其中电压外环保证了稳定的直流输出，电流内环提高了电流的动态响应速度，并且这种控制方法使电流的相位和输入电压的相位保持一致。(1, based on Ip/Iq way to control the PWM rectifier to achieve the active and reactive decoupling control of DC capacitor voltage control. 2, respectively, using hysteresis current and voltage space vector PWM modulation technique 3, DSTATCOM reactive power compensation simulation 4, the system used in the decoupling control with feed-forward on the basis of the voltage and current double closed-loop control structure, in which voltage outer ring to ensure a stable DC output, current inner improve current dynamic response, and this control method makes the current phase and the phase of the input voltage is consistent.)

resistive and inductive load. simulation also demonstrate the role of free wheeling diode. Single phase pulse generator was developed to generate the pulses at required firing angle.
