Abstract
As is known, a semi-magic square is an n 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.
