Question

Write MATLAB code to reproduce the figure and ensure the following:

  • Add clear all; close all; clc; at the start of the script
  • An anonymous function is used to define y = @(t,xi,omega) ...
  • omega = 10.26
  • is a vector from 0 to 1 (inclusive) with 200 points
  • The line colour specifications are MATLAB's default and do not need to be explicitly stated
  • The title and axes are labelled accordingly
  • Top subplot:
    • xi is a vector from 0.2 to 0.8 with increments of 0.2
    • for loop is used to go through each xi value
    • The legend can be hardcoded and is positioned in the 'best' location
  • Bottom subplot:
    • xi = 0.65
    • The maximum point is marked with a diamond
    • The grid is turned on
    • The legend can be hardcoded and is positioned in the south-east corner
Expert Solution
Step 1

clear all; close all; clc; y = @(t,xi,omega) (1-xi^2)^(1/2)*cos(omega*t); t = 0:1/200:1; subplot(2,1,1); for xi = 0.2:0.2:0.8 plot(t,y(t,xi,10.26)); hold on; end title('For Loop'); xlabel('t'); ylabel('y'); legend({'0.2','0.4','0.6','0.8'},'Location','best'); subplot(2,1,2); plot(t,y(t,0.65,10.26),'Marker','d','MarkerSize',8); title('xi = 0.65'); xlabel('t'); ylabel('y'); grid on; legend({'0.65'},'Location','southeast');
