MATLAB  Links

We will be using MATLAB during EECE 301 for demos and assignments.
There will be a Tutorial during an early Discussion section to get you started with MATLAB
(See the link to my MATLAB Tutorial above in the section "Discussion Notes" ).

Here are some other tutorial links you might find useful:

• MATLAB Getting Started Links
  • MATLAB Getting Started (Web Link)
  • MATLAB Getting Started (Download pdf file from Mathworks' Web Site)
