= Jordan basis
{c}

A Jordan basis is a <basis> consisting of <Jordan chains> of <generalized eigenvectors> for a <linear operator>. Its <matrix> is in <Jordan normal form>. Over the complex numbers every finite-dimensional <linear operator> has such a <basis>; a real matrix with nonreal <eigenvalues> requires complexification for this form.
