This is for MATLAB% Section 1 clear variables; close all; clc; % Use the "Run Section" button as you complete this script % Given the matrix A and the vector B A = [ 1 -4 2 -2 3 3 5 2 1]; b = [ -2 3 5]; % Calculate the product of A x B in the space below (grade = 10 points) % Calculate the product of inverse(A) x B in the space below (10 points) % Calculate c = the numeric value in the second row and % first column of matrix [A] in the space below (10 points) %% Section 2 clear variables; close all; clc; % Create a variable x = range of 10 numbers % between -pi and pi (radians) (grade = 10 points) % Set y = sin(x) in the space below (10 points) % Set z = x * sin(x) in the space below (10 points) % HINT: You will need the .* for this operation instead of * % Plot y and z versus x between the "hold on" and "hold off" commands % Label the x and y axes properly and use appropriate units (10 points) % use xlabel('Angle (Radians)') % use ylabel('sin(x) and x sin(x)') % Plot y using a blue line with circular markers (10 points) % On the same plot, include z using a red line with triangular margers % (1 point) % use legend('sin(x)','x sin(x)') (10 points) hold on
