Hakopian, Y. R.; Eloyan, A. N.
International Journal of Mathematical Education in Science and Technology, v38 n8 p1093-1102 Dec 2007
As is known, a semi-magic square is an "n x n" matrix having the sum of entries in each row and each column equal to a constant. This note generalizes this notion and introduce a special class of block matrices called "block magic rectangles." It is proved that the Moore-Penrose inverse of a block magic rectangle is also a block magic rectangle.
