We are going to start exploring the Discrete Fourier Transform (DFT) as Change of Basis. Exploring the Fourier Basis DFT is a powerful tool for analyzing signal. At its core, the DFT is a simple change of Basis. In this blog entry, we will explore and generate some of the Fourier Basis. We will…

Macros in Julia are a very nice element of the language. You can easily visually identify macros as they are called using the@ prefix. I most often use the@assert, @show, @spawn, @edit, and @time macros. However, one needs to understand how macros work to confidently use them. Today I want…
