I have raw data in following format(adsbygoogle = window.adsbygoogle || []).push({});

Time <-> Ch1 <-> Ch2 <-> Ch3

0.01 <-> 1.6 <-> 1.62 <-> 1.92

0.03 <-> 1.63 <-> 1.62 <-> 1.96

0.05 <-> 1.63 <-> 1.63 <-> 2.04

..........so on 1000 raw

PS: those <-> are used in this forum to show as table, in actual data those are separate column.

How can I plot FFT in matlab from this data ?

Do I have to convert anything first ?

I am newbi to matlab, any help would be greatly appreciated.

Thanks a lot in advance.
