clear % Homework D = diag(-rand(2,1)); % random diagonal matrix of 2 negatives eigenvalues v1 = rand(2,1); v2 = rand(2,1); %v1=v1/norm(v1); %v2=v2/norm(v2); V = [v1, v2]; r1=V(1,:); r2=V(2,:); %V = rand(2,2); % rotation matrix, the angle of rotation is pi/6 for k = 0:0.001:1/3 R = [cos(k*pi), -sin(k*pi); sin(k*pi), cos(k*pi)] k
r11 = r1*R; r22 = r2*inv(R); V1 = [r11;r22];
end %V1 = V*R A = V*D*inv(V); D1 = diag(-rand(2,1)); A1 = (V1)*(D1)*inv(V1); figure(1) p = (log(norm(inv(V)*V1)) + log(norm(inv(V1)*V)))/(-max(eig(A)) – max(eig(A1)))
plot(k,p) xlabel('k') ylabel('p')
can u help me to plot this ? the plot shows only a point in space thanks
