Yes, but it won't give anything useful to you; you'll end up with output like an identity matrix.

Can this Modified Gram-Schmidt Orthogonalization be applicable to linearly dependent vectors ?

function Q = mgs(A)

n = size(A,2);
Q = A;

for k = 1:n-1,
Q(:,k) = A(:,k) ./ norm(A(:,k));
A(:,k+1:n) = A(:,k+1:n) - Q(:,k) * (Q(:,k)' * A(:,k+1:n));
end;
Q(:,n) = A(:,n) ./ norm(A(:,n));

??? Index exceeds matrix dimensions.
