WebMatrix Multiplication. You can only multiply two matrices if their dimensions are compatible , which means the number of columns in the first matrix is the same as the number of rows in the second matrix. If A = [ a i j] is an m × n matrix and B = [ b i j] is an n × p matrix, the product A B is an m × p matrix. WebThe product of 'any matrix' and the appropriate identity matrix is always the original matrix, regardless of the order in which the multiplication was performed! In other words, A*I=I*A=A I think this only work when the matrix A is square matrix. For example, we …
