步进电机s型加减速曲线，实现对加减速的不同控制

图像处理MATLAB源代码，这个是哈夫曼编码(huffman)

最近总是遇到调音量和选择录音通道方面的程序，我从网上下载了一个音量控制类，但在不同的操作系统有时会出错，我修改了里面的错误，重新封装成dll类，并提供详细的测试程序。没什么技术只是为了方便使用。 不过这个类在某些操作系统上对录音通道选择时还是会出问题，比如明明是选择"Mono"录音通道，可他却选到其他通道了， 我用了DirectX自带的例子程序也不能正确选到想要的录音通道，不知道如何能准确地选择需要的录音通道，若有高手知道请不吝赐教，我的E-Mail:chrys@163.com，多谢！(recent encounter always stressed the volume and channel selection recording of the procedures, I downloaded from the Internet by a volume control category, but in different operating systems sometimes be wrong, I revised the inside of errors, dll encapsulation into categories, and to provide detailed test procedures. No technology is meant to facilitate use. But in the category of some systems of recording channels to choose or will be problems, For example, she choose "Mono" recording channel, but he elected to the other channel, I used the example of DirectX, bringing their procedures for the election not to want to correct audio channel, do not know how to accurately select the desired audio channel, if experts know Help us to assume my E-Mail : chrys@163.com, thank!)

自己动手写操作系统，小练习包括fifo.cfork.cpopen.c等，保护模式，超过1M内存管理模式，等代码，生成的中间文件等，适合初学者参考！(Do-it-yourself write operation system, small exercises include fifo. C fork. C popen. C, and other protection mode, more than 1 M memory management mode, and the code, generation of the middle of the documents, etc, and is suitable for beginners reference )

Energy efficiency is the most important design goal for wireless sensor networks (WSNs). In this paper, we propose an energy-efficient cooperative MIMO scheme, which combines energy-efficient LEACH (EE-LEACH) protocol and cooperative MIMO. We name it as EE-LEACH-MIMO scheme. EE-LEACH is an improved LEACH algorithm, in which the network is partitioned to sectors with equal angle for avoiding the distribution non-uniformity of cluster heads. In EE-LEACH-MIMO scheme, the location and the residual energy of each node are considered when the cluster heads for clustering and cooperative nodes for MIMO system are chosen. For comparisons, LEACH, EE-LEACH, the simple cooperative scheme with LEACH and MIMO (LEACHMIMO), and EE-LEACH-MIMO scheme are simulated. The result shows that EE-LEACH-MIMO scheme can well balance the network load, save energy and prolong the network lifetime

本代码是PID在S函数中的实现，但不同之处在于，本代码先把PID变成状态空间表达式，更加易懂，为本人独创。(This code is the PID in the S function, but the difference is that, this code to put the PID into the state space expressions, more understandable, for my original.)
