这是MATLAB的控制工具箱。由薛定宇教师编写。这个工具箱用来实现的PID最优程序！(This is the control MATLAB toolbox. Xue prepared by the teachers. This toolbox used to achieve the optimum PID process!)

对matlab初学者很有帮助，尤其是simulink的爱好者。(helpful to beginners Matlab, Simulink is particularly fond.)

本源码通过声音传通数据，将数据调制二进制PSK(即BPSK)信号从喇叭发出来，另外一个接收程序接收到声音后，便可以解码出来，用到的技术有PSK编码、PSK解码、Windows录音，为了防止传输过程中出现的误，本原码采用rss纠错码，使得通讯更加稳定可靠。(The Source by voice through the data, binary modulation PSK (ie, BPSK) signals emitted the speaker, the other receiving program after receiving the sound, you can decode it, the techniques used have PSK encoding, PSK decoding, Windows Recording in order to prevent accidental transmission occurs, the primitive code using rss error correction code, making communications more reliable.)

经典matlab书籍——《精通MATLABA6.5版》，张志涌等编著，北京航空航天大学出版社。配备书上详细的代码，学好MATLAB必备。 (Matlab classic books- proficient MATLABA6.5 Edition , edited by Zhang Zhiyong, etc., Beijing University of Aeronautics and Astronautics Press. Books with detailed code, learn essential MATLAB.)

信源编译码仿真，信道编译码仿真，数字调制解调仿(Simulation of the source codec, channel coding simulation, digital modulation and demodulation simulation)

基于matlab的异步电动机仿真控制，控制方式为svpwm波，输出结果理想。(Based on simulation matlab induction motor control, control of svpwm wave output ideal.)

读取BMP文件信息和显示，读取文件头信息，包括大小，长宽，水平和垂直分辨率，彩色数目，实际用到的彩色数目，关键颜色数目，压缩方式，每像素用到的bit数等(to read and display bmp file. output the header information, includnig file size, image width and height, horizontal and verticular resolution, number of color used and number of significant color, compression method, bit count per pixel etc.)
