Let’s compare it to an operation we discussed earlier. In Equation 1.12, we pointed out the subscripted expression MijNjk represented the regular matrix product [M] [N]b, ecause the summed subscript j is in the second position of the [MI matrix and the first position of the [N] matrix. The expression R,R,,, however, has a contraction over the first index of both matrices. In order to make sense of this product, we write the first instance of [R] using the transpose:
