WebOct 6, 2024 · You are dividing a vector by a matrix since mat1 [1, ] is a vector not a matrix. R processes the matrix in the denominator by columns so in your first example: 46/80, 30/74, 25/71, etc because in the transposed matrix, the first column is grade4 schools. When the matrix is not transposed, the first column is schoolA and you get 46/80 , 30/90 ... WebYou had part b right, but you can't always multiply two matrices with the same dimensions. Take your example [1x3] * [1x3]. They are both 1x2 matrices. Since the the number of columns of the first matrix isn't equal to the number of rows of the second (2 and 1) this operation is undefined. :D Hope this helps! 2 comments ( 9 votes) Upvote Flag Arya
