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(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)

采用稀疏矩阵的PQ分解法潮流计算程序（依据《电力系统计算》一书附录用C语言编写，使用方法、变量名称都与书上一致）(Decoupled load flow)

函数逼近教学例子,可以选择不同训练算法。(Function approximation teaching example, you can choose different training algorithms.)

很实用的一个OFDM仿真程序，OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图，将每个子信道上的数据，映射到星座图点的复数表示，转换为同相Ich和正交分量Qch。(A very practical OFDM simulation program, OFDM the BPSK, QPSK, 16 qam, 64 qam4 kind of modulation method. According to the constellation diagram, each will be the data on the channel, the plural of constellation is mapped to a point, said into in-phase Ich and quadrature Qch. )
