PSCAD仿真出的波形如何在MATLAB中进行FFT

不懂就问

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。

怎么将pscad的故障波导出到matlab，再进行进行小波变换分析呢？

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

    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。
