Split quaternions, as an extension of classical quaternions, exhibit distinct algebraic properties and offer valuable applications across various fields. This paper investigates solutions to the split quaternion matrix equation ?l,i=1 AiXiBi = C, providing necessary and sufficient conditions for its solvability and expressions for various types of solutions. Solvability criteria and explicit solution forms are derived for general, pure imaginary, and real solutions. Additionally, corresponding conditions and expressions are presented for (skew-)centro-Hermitian solutions. Finally, numerical examples and algorithms are provided to validate the accuracy of the obtained results.
