关于soft matting的MATLAB代码(A closed form solution to Natural Image Matting A. Levin D. Lischinski and Y. Weiss )

这个程序是matlab用来来对锁相环（PLL）进行仿真的，这样的选择基于多方面的考虑(This procedure is used Matlab to the phase-locked loop (PLL) simulation, This choice is based on a number of considerations)

说明：  基于dct的数字水印技术，能够应用于版权技术等方面，希望能与大家分享。(Dct-based digital watermarking technology can be applied to other aspects of copyright technology, hoping to share with you.)

蔡氏混沌电路的控制，主要有线性控制，非线性控制，微分控制，等其他控制，完整的程序和方程。(Chaotic circuit control, linear control, nonlinear control, differential control, and other control, complete the procedures and equations.)

说明：  matlab时针程序，能实现双时针的配合旋转，历时24小时(The matlab clockwise procedures to achieve dual-clockwise with the rotation, which lasted 24 hours)

2PSK、QPSK、8PSK等多种调制方式及瑞利信道和高斯信道下误码率的比较分析( 2PSK, QPSK, 8PSK and other Rayleigh channel and Gaussian channel under the bit error rate comparison and analysis)

FFT的matlab程序，老师编的，很实用。

power_svpwm_multiPhasesLevel_sfun.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_svpwm_multiPhasesLevel_sfun.rar, Power electronics field matlab simulation file, has already been verified, the normal operating procedures)
