ANSWER:
Solution 9E
Step 1 of 3
The objective is to find the list of using power method for the following matrix:
Use MATLAB to find the list.
Code for MATLAB:
function[x,lambda]=powermat(A,x0,nit) x = x0; for n=1:nit xnew = A*x; lambda = norm(xnew,inf)/norm(x,inf); fprintf('n = %4d lambda = %g x = %g %g %g \n', n, lambda, x');
x=xnew; end x=x/norm(x);%normalise x fprintf('n = %4d normalised x = %g %g %g\n', n, x');
