New positon, negaton, and complexiton solutions of a coupled Korteweg–de Vries – modified Korteweg–de Vries system are constructed directly from the zero seed solution by means of Darboux transformation with different constant selection. The positon, negaton, and complexiton solutions are given out analytically and graphically.
Key words: Positon; Negaton; Complexiton; Darboux Transformation.
