How to remove periodicity in hourly wind speed data by using fourier transform

Hey, I have a dataset that contains hourly wind speed data for 7 seven. I am trying to implement a forecasting model to the data and the review paper states that trimming of diurnal, weekly, monthly, and annual patterns in data significantly enhances estimation accuracy. They then follow along by using the fourier series to remove the periodic components as seen in the attached picture. Any ideas on how i model this in matlab? I am need of help urgently!!!!
