改变窗长的相位差离散频谱校正源程序。改变窗长的相位差校正程序，可选择矩形窗和汉宁窗。已调试通过。(Matlab Codes for phase difference correction based on different window.Rectangle and Hanning Window can be choose to act.)

How to do FFT spectral analysis

说明：  MATLAB辅助变量法算实例，算法简单，计算量少(Operator-assisted MATLAB instance variables, the algorithm is simple, computing less)

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)

matlab环境下的前推后代法潮流计算程序，是7个节点的配电网。(before pushing sweep method flow calculation program matlab environment, the distribution network is seven nodes.)

说明：  对uwb的ppm调制的时域和频域进行分析,画出它的图形(ppm of UWB modulation of the time domain and frequency domain analysis, to give its graphics)
