Fourier Transforms and Time Series Data

I’m doing a talk at Big Data Brighton on April 25th. I will add the slides after but for now I’ll put up the matlab m file scripts. All at:

Slides for Time Series Data and FFT

This shows a single sinusoid and Fourier Transform
This is the example which takes several sinusoids, sums them and shows their Fourier Transforms

This is the filtering example
