Matrices and Linear Functions
... It is important to note that in order for the product of two matrices to be defined their dimensions must agree in a certain way. The second dimension of A must equal the first dimension of B (i.e. A must be l × m and B must be m × n). Thus, even though AB might make sense it is possible that BA doe ...
