Procedures: In this lab, we want to check our understanding with MATLAB plotting 2D figures. Plotting is important as it can ilustrate quick and relevant information to the audience. In this lab, we are going to plot 2D figures. The functions to plot are: y1 = y2 = cos(x3) Part1: The x-axis starts from -3 to 3 with a 100 number of points. You need to add a title This is a 2D plot using MATLAB You need to name the x-axis and y-axis with any name you prefer . You need to add grid on . You need to add legend and name each data set with any name you prefer. Both data sets should be in one plot only y should be green and should be blue Part2: For this part, you need to repeat part but now each data set should be in one plot but both plots should be in one figure. (Hint: use subplot function) Submission: Make sure to add the 3 commands for clearing the command window, clearing the Workspace and to close all the plots if any. Comment your nameamesinine 4 in your code . in fine 5. comments your student IDI IDs Each part should be in a new script Submit only four files (script1, script2, figure 1 & figurez)
