Two matrices C and D can be multiplied only if number of columns in C is same as number of rows in D.
Here A is a [1×2] matrix, B is [2×3].
Hence the product AB will be a [1×3] matrix.
Applying the rules of matrix multiplication,
In order to find BA, B is a [2×3] matrix, hile A is [1×2].
Number of columns in B is 3, number of rows in A is 1.
Therefore this multiplication can not be done. In other words the product BA will be undefined.
