hi,

is there an explicit solution for:

$\displaystyle
u_t = \imath\left(\begin{array}{cc}0&1\\1&0\end{array}\r ight) u_{xx} -\displaystyle{\frac{1}{2}} \left(\begin{array}{cc}7&-1\\-1&7\end{array}\right) u
$


$\displaystyle
u(x,0) = \left(\begin{array}{cc}cos\omega x\\-\imath sin\omega x\end{array}\right)
$
