我是个菜鸟,刚学pscad不久,MATLAB也不怎么会。现在我要将在PSCAD中仿真出的波形进行频谱分析,于是将波形导出到了A.TXT文件中,然后用MATLAB进行读取,分析。这里遇到一个问题,我怎么对这些数据进行FFT变换,波形函数需不需要表示出来?请问各位高手,我应该怎么办。附件A是我的波形数据和matlab中的画出的波形。

    你导出也就是一堆的数,在matlab里分析的也是一堆数,平时怎么分析就怎么弄好了

    + ~3 r3 o  l' R; U4 J$ T* S( S    我以前发过类似的帖子,在PSCAD中可以进行动态FFT分析。但是不能直接显示为MATLAB中那种柱状图,把数据导出后要进行稍微处理一下,变成y=(Am,50n(n=1、2、3...)形式,在用plot或figure。
