**Instance of Code for the QR Algorithm in MATLAB**

To execute the QR algorithm in MATLAB, we provide a simple instance:

function [eigenvalues, eigenvectors] = qr_algorithm(A, tol, maxIter)

% QR Algorithm to compute eigenvalues and eigenvectors

% A – Input square matrix

% tol – Convergence tolerance

% maxIter – Maximum number of iterations

% Initialize variables

n = size(A, 1);

Q_total = eye(n);

iter = 0;

converged = false;

while ~converged && iter < maxIter

iter = iter + 1;

% Perform QR decomposition

[Q, R] = qr(A);

% Update matrix A

A = R * Q;

% Accumulate the orthogonal matrix Q

Q_total = Q_total * Q;

% Check for convergence

off_diagonal = A – diag(diag(A));

if norm(off_diagonal, ‘fro’) < tol

converged = true;

end

end

% Extract eigenvalues and eigenvectors

eigenvalues = diag(A);

eigenvectors = Q_total;

if converged

fprintf(‘QR algorithm converged in %d iterations.\n’, iter);

else

fprintf(‘QR algorithm did not converge within the maximum number of iterations.\n’);

end

end

% Example usage

A = [4, 1, -2, 2;

1, 2, 0, 1;

-2, 0, 3, -2;

2, 1, -2, -1];

tol = 1e-6; % Convergence tolerance

maxIter = 1000; % Maximum number of iterations

[eigenvalues, eigenvectors] = qr_algorithm(A, tol, maxIter);
