Hi all,

I want to find eigenvalues of the following block matrix X:

$\displaystyle

X = \left[ \begin{array}{cc}

2U-V & -V \\

-V & 2U-V \end{array} \right]

$,

where U and V are n-by-n block matrices and so the X is a 2n-by-2n matrix.

Can I further simplify the equation? I'm looking for solutions like eig(...).

Thank you for your any advice and comment in advance.

Thanks,

Jong
