Herewe have to multiply 3 × 2 matrix and 2 × 2 matrix, which is possible and the resultant matrix will be 3 × 2. Let us understand with the help of an example. Let A = 0 7 3 6 - 2 0 and B = 3 - 4 0 12. then, A B = 0 × 3 + 0 × 7 - 4 × 0 + 7 × 12 3 × 3 + 6 × 0 - 4 × 3 + 6 × 12 - 2 × 3 + ( - 2) × 0 ( - 2) × ( - 4) + 12 × 0. = 0 84

Remarks The identity matrix is the 3x2 matrix with ones on the main diagonal and zeros elsewhere. When an identity transform is applied to an object, it does not change the position, shape, or size of the object. It is similar to the way that multiplying a number by 1 does not change the number. Any transform other than the identity transform

Asyou see in your example, the middle terms MUST be the same in order to multiply matrices, the resulting matrix will be the size of the two outside numbers, so you would end up with a 3x1 matrix. If you tried to reverse positions and did 2x1*3x2, the middle numbers are not the same, so they cannot be multiplied.
Sortedby: 1. For a diagonal n × n n × n matrix, it is not very hard to check that. (D(a1, ,an))t = D(at1, ,atn). ( D ( a 1, , a n)) t = D ( a 1 t, , a n t). For A3 A 3 and A4 A 4, just compute the first values to find that. A23 = 0, A24 =⎛⎝⎜0 0 0 0 0 0 1 0 0⎞⎠⎟, A34 = 0.
