UPSAMPLING AND DOWNSAMPLING

说明：  TDFD,双脊金属加载矩形波导，的基模和第一个高阶模的色散曲线计算,TE模的仿真(TDFD,双脊metal loaded rectangular waveguide, the fundamental mode and first higher order mode dispersion curve calculation, TE-mode simulation)

功能列表= mmwrite（文件名，选择... ...） mmwrite是能写的AVI，WMV，的WMA，ASF文件。对于AVI文件，您可以选择从现有的编解码器压缩的音频和视频流。 对于WMV，WMA和ASF的编码默认为16位的Windows Media 9率为44100Hz立体声为98％质量的音频和Windows媒体视频9 98 质量。质量可以指定音频和视频。 环绕声，似乎只与AVI和多通道编码不支持。编写任何其他文件类型不支持。本使用Windows的DirectX基础设施，以便其他操作系统是出于运气。 输入：     文件名：这一定是第一个参数，并指定文件名写。     影片结构：视频结构相匹配的mmread输出。在最低限度，必须有4个领域的“框架”，“时代”，“高度”和“宽度”。该“框架”字段必须是一个结构与一个字段数组“的CDATA”的原始框架，它包含由彩色编码的数据宽度高度（3）UINT8s。钍(function list = mmwrite(filename,...options...) mmwrite is able to write AVI,WMV,WMA,ASF files. For AVI files you can choose from the available codecs to compress the audio and video streams. For WMV,WMA and ASF the encoding defaults to Windows Media 9 44100Hz 16bit stereo 98 quality for the audio and Windows Media 9 Video with 98 quality. The quality can be specified for both audio and video. Surround sound only seems to work with AVI and multi-pass encoding is not supported. Writing any other file type is not supported. This uses Windows DirectX infrastructure, so other OSs are out of luck. INPUT: filename: This must be the first parameter and specifies the filename to write. video structure: The video structure matches the output of mmread. At a minimum it must have 4 fields "frames", "times", "height" and "width". The "frames" field must be a struct array with a field "cdata" that contains the raw frame data encoded as height by width by color(3) as UINT8s. Th)

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.)

说明：  这是我在学习matlab时写的一些简单的图形处理的例子,初学者可以看一下!(This is my matlab when learning to write some simple examples of graphics processing, a beginner can look at!)

Image reconstruction based on wavelet transform. is very useful to people who want to learn about image reconstruction

Cheby 四种基本滤波器(Cheby four basic filter)

Object tracking in computer vision refers to the task of tracking individual moving objects accurately from one frame to another in an image sequence. Several tracking methods have been proposed in the recent literature capable of coping with a certain degree of occlusions of the objects.

说明：  这是基于matlab的单用户注水算法的源程序，(This is a matlab-based algorithm for single-user water source,)

本例主要说明了空间域滤波与频域滤波的比较！在空间域中采用了Sobel掩膜对f滤波的结果与在频域中进行等价操作的结果！(This example illustrates the spatial filtering mainly with the comparison of frequency domain filtering! In the spatial domain using the Sobel filter mask on the results of f in the frequency domain is equivalent with the result of the operation!)
