I have an array X that contains a column with numbers from a time signal of 40hz sample. I want to find the main frequency component (MFC) of that array. I tried using ftt(X) function in matlab which returns a new complex array Y. What are the next step to find the MFC and the amplitude of MFC?

From my understanding you want to find frequency of signal in FFT. Here (link1 and link2) is a similar question which might help you.

To be honest, i'm not sure what i'm searching exactly. I have data from the accelerometer on the phone from x,y,z axis and i need to find the main frequency component. (It's a task from uni, that i have to do, so that's why i don't know what i'm looking for)
