  ABSTRACT: This paper addresses a class of numerical solution problems for quaternion quadratic matrix equations arising from practical engineering applications. By transforming it into a special Riccati equation, a sufficient condition for the existence of solutions to the corresponding M-matrix equation is derived using the theory of comparison matrices. This condition is then applied to investigate the existence of solutions for the quaternion quadratic matrix equation. Finally, numerical examples demonstrate an effective solution method for the quaternion quadratic matrix equation using fixed-point iteration.
