I spend a majority of my work day using Matlab and writing Matlab code. I work on a variety of projects that involve advanced signal processing and high-fidelity simulations that are all written in Matlab. I also use Matlab for all my day-to-day analysis efforts. This page has a variety of Matlab examples that you may find useful.
The code used in these examples can be download in the Members Only portion of the website
