Assignment 4 For this assignment refer to the notes on MATLAB from an MIT course that you can find here (or at the original website, lectures 14, 15, 16). Consult the lecture material as needed. However, your best guide for this assignment is MATLAB demo, callable from Help menu. 1. Answer Question 3 from this assignment. The referred to assignment 1 and its solution may be found here. 2. For the MATLAB code in our first class, design a simple GUI that will have the following features: will accept and verify user’s input for nhd_size parameter (the parameters that determines the size of the matrices we work on, recall that nhd_size has to be a multiple of 2), that is, if user’s input is incorrect, e.g., negative value or not a multiple of 2, etc., the user will be asked to correct the mistake, will have a Run button that executes the local search. For a), you will need to use Edit control as was demonstrated in class. For message display you might use Text control, etc.
