matlab实现excel格式的数据的快速傅立叶变化程序-matlab excel format data fast Fourier transform program

从Excel表中读取数据，然后分析其频谱、相谱和总谐波畸变率，并画出图（plot）。-Read data from an Excel table, and then analyze its spectrum, phase spectrum and total harmonic distortion rate, and draw the diagram (plot).

MATLAB 小程序，进行FFT计算，将原始数据放入EXCEL，运行M文件，进行频谱分析-MATLAB applet, the FFT calculation, the raw data into EXCEL, run M files, spectral analysis

由两组已知的振动波形数据（excel表格形式），运用matlab生成对应的波形，利用FFT生成频谱图。要求将所有图像生成在一个图框下。包含设计文档和代码(Two groups of known vibration waveform data (excel form), using MATLAB to generate the corresponding waveform, using FFT to generate spectrum. Contains document reports and
