mefig function for wavelet analysis

白色噪声的生成数据,自己编写,可以直接使用(The white noise generated data, write your own, you can directly use)

对MIMO中的瑞可接收机进行仿真，绝对可以运行的 (On the MIMO receiver in Sweden can be simulated)

信号源的emd分解，得到imf分量，以及imf分量的时频图。(The signal source EMD decomposition, the IMF component, as well as the imf component time-frequency diagram.)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

白噪声频谱。掌握白噪频谱在去除噪声时很重要，尤其噪声背景很强时(noise)

说明：  基于P-Q分解法的潮流计算适合初学者学习程序简单易懂(PQ decomposition method based on the trend of the calculation procedure for beginners Learn easy-to-read)

matlab的一些实例，希望对大家有帮助(matlab some examples, we want to help)

it is a matlab mdl file to generate c code for ccs software without any manual modification
