ABSTRACT:
The fundamental solution (Green's function) of a first order
matrix ordinary differential equation arising
in a Landau-type problem is calculated by two methods.
The coincidence of the two representations results in the integral
formula for the product of two parabolic cylinder functions
$D_\nu(x)D_\nu(-x)$ at $\Re\nu<0$, $x\in\Bbb R$.
