Suppose we are multiplying matrix $A$ with a diagonal matrix $D$ from left, i.e.,
$X=D A$
where $D$ is a diagonal matrix with elements
$$d_{ii}=\frac{1}{2} \text{ for } i=1,n$$
$$d_{ii}=\frac{1}{3} \text{ for } i =2, \dots, n-1.$$
Is there any relation with the set of eigenvalues of $X$ and $A$ (like any lower bounds on the eigenvalues)?
