自己编写的svm多分类1对1的程序，如果有错误，请帮忙改正(I have written more than svm classification procedure 1 to 1, if there is an error, please help correct)

压缩包里面有四个程序：在matlab中对图像进行过滤操作和频率操作，和函数的变换(Compressed inside four programs: the transformation of image filtering operation and the frequency of operation, and function in matlab)

this is a matlab code for quantom pso algorithm coding.

很好的介绍语音增强的论文资料，包括各种算法的MATLAB的实现程序，可供读者学习运用。(very good for studying pitch.)

这是本人自己遍的matlab程序，即对做过fft变换的相位嵌入水印的程序(this is my own times of Matlab procedures, that is done on the phase transformation fft watermark embedding procedures)

说明：  Simulink中实现PR控制器。PR控制器在逆变器控制中应用很多。PR控制能够在谐振频率处提供无穷大的增益，因而对谐振频率处的电流信号实现无静差跟踪，并且易于实现，可有效降低系统成本。(PR controller is implemented in Simulink. PR controller is widely used in inverter control. PR control can provide infinite gain at the resonant frequency, so the current signal at the resonant frequency can be tracked without static error, which is easy to implement and can effectively reduce the system cost.)
