Summary:A simple analog rank filter structure is proposed. A matrix-valued
ordinary differential equation (ODE) with initial conditions performs
the sorting. The state realization of this ODE contains integrators,
adders, and multipliers. The multiplication operations make the filter
nonlinear. The structure is a regular array that is only locally
connected
