代码说明:

  Matlab编程实现FFT变换及频谱分析的程序代码(适合初学者加强理解)。(1)用Matlab产生正弦波,矩形波,以及白噪声信号,并显示各自时域波形图;(2)进行FFT变换,显示各自频谱图,其中采样率,频率、数据长度自选;(3)做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱;(4)用IFFT傅立叶反变换恢复信号,并显示恢复的正弦信号时域波形图。(Matlab codes for FFT Understanding which contains sine wave,rectangular wave and the reletaed frequency spectrum figure about MSE,Log,IFFT and so on.)

  • rnnsim
    RNNSIM ver. 1.0 is a program with an intercative graphical user interface (GUI) that runs under MATLAB ver. 5.0 or higher. The program can be used in training and testing the Random Neural Network(RNN) models. This version (ver. 1.0) implements only the 3 layer feed forward RNN model. In the next versions, the multi hidden layers and the recurrent RNN models can be implemented. To obtain faster training, the training section can be written as a MEX file and invoked from the GUI. If you have the m files in the directory rnnsim for example, then you can run the program following the next steps: 1- run MATLAB as usual 2- from the MATLAB command window, write cd rnnsim 3- from the MATLAB command window, write rnnsim
