In this article, we completely determine when a 2 x 2 matrix over a commutative local ring is strongly rad clean. An application to matrices over power-series is also given.enCC BY 4.0 DEED (Attribution 4.0 International)Strongly clean matrixstrongly rad-clean matrixlocal ringpower-seriesArticle10.5666/KMJ.2023.63.4.5610454-8124
