On the inverse of the sum of matrices

Web6 de jan. de 2024 · Abstract. The paper considers various problems concerned with the Moore–Penrose inverse of a sum of two matrices. By establishing several original results and by combining various facts known in the literature, the article reveals a number of emerging features of the inverse. The investigations shed also a spotlight on different … Web17 de set. de 2024 · The part before “is” states that we take the transpose of a matrix, then find the inverse. The part after “is” states that we find the inverse of the matrix, then take the transpose. Since these two statements are linked by an “is,” they are equal. [5] These examples don’t prove anything, other than it worked in specific examples.
