Question-Solved

Post Body

Hey everyone,

I'm currently working on a project where I need to identify the frequencies that correspond to various peaks in my FFT plot. Although I'm aware that the maximum frequency is the Nyquist limit, and I can work backwards in intervals of 1/2 to figure out the other frequencies, this method is highly imprecise and doesnt give me the exact, specific results I need for the specific peaks. I've tried reading around the internet, but I can't seem to figure out how to convert it within MATLAB itself from bins to hertz.

My code can be found here: https://pastebin.com/6fwkQzbw

And a plot of my FFT is here: https://imgur.com/a/ofo8p

Thank you so much for your help!
