Also, we present many theorems that concern the computing of their eigenvalues and eigenvectors and their connection with classical ordinary matrices. Many related examples will be provided to clarify the validity of our work. 2023 08 17 2016 https://creativecommons.org/licenses/by/4.0/ 10.54216/GJMSA.070101 https://americaspg.com/journal/33/article/2016 https://americaspg.com/storage/51749391624.pdf
