BME 6360 Homework #3 Spring 2011 Neural Engineering Prof. Wheeler Introduction to Simulink The goals of this exercise are three: A. To acquaint you with Simulink. B. To have you create your own simulation. C. To introduce to you a simple simulator which creates neural spike trains from analog input. D. To practice including Simulink output in word processor documents. Do not be intimidated by the length of this document: we have included lots of screen images of the various menus and displays which you will encounter Files You Need: You will need to use the following course files: vor1.m and spiker.m A. GETTING TO KNOW SIMULINK 1. Getting Started: Start up Matlab and simply type: vor1 This should start a previously written Simulink file. If not, the following are instructions on how to change Matlab's search path so that it can find the file. If you have successfully opened the file, and you should see the wiring diagram below. If you do not see a scope window, double click on the scope icon. 2. Run the simulation. Choose the simulation menu and select start: the simulation should run with a visible result on the scope.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
