In this paper we describe a new computational operator, called generalized
complex entropic form (GEF), for pattern characterization of spatially exte
nded systems. Besides of being a measure of regularity, this operator permi
ts to quantify the degree of phase disorder associated with a given gradien
t field. An application of GEF to the analysis of the gradient pattern dyna
mics of a logistic Coupled Map Lattice is presented. Simulations using a Ga
ussian and random initial condition, provide interesting insights on the sy
stem gradual transition from order/symmetry to disorder/randomness. (C) 200
