Eigenvalues and Jordan Forms of Dual Complex Matrices [PDF]

open access: yesCommunications on Applied Mathematics and Computation, 2023
Dual complex matrices have found applications in brain science. There are two different definitions of the dual complex number multiplication. One is noncommutative. Another is commutative. In this paper, we use the commutative definition.
