Hello, I am a new MATLAB user. I had a signal file in .txt which I did Fourier Transform for. I would like to know what code I should input in MATLAB in order to plot the phase and amplitude spectra of this file. Thanks in advance... "The signal txt is atttched herewith"

Strider, This is the only data given to me by my lecturer in college, I don't need accuracy but can you give me a code that allows this to do the above mentioned program. I know that the data is incomplete, But can you give the specific time vectors by yourself and do the 2 plottings. Take the sample rate of 100samples/second or deltaT = 0.01.
I will be highly grateful.
