heal.abstract	The numerical range of an n£n matrix polynomial P(‚) = Am‚m + Am¡1‚m¡1 + ¢¢¢ + A1‚ + A0 is defined by W(P) = f‚ 2C : x⁄P(‚)x = 0; x 2Cn; x⁄x = 1g; and plays an important role in the study of matrix polynomials. In this paper, we describe a methodology for the illustration of its boundary, @W(P),	en
