Properties of Matrix Multiplication
Matrix multiplication is not commutative in general. Matrix multiplication is associative i.e., (AB)C = A(BC), whenever both sides are defined. Matrix multiplication is distributive over matrix addition i.e., ..

Commutator
A commutator is used to reverse the direction of flow of current. Commutator is a copper ring split into two parts C 1 and C 2 . The split rings are insulated form each other and mounted on the axle of the motor. The two ends of the coil are soldered to these rings. They rotat..
Multiplication of a matrix by a scalar
Let A=[a i j ] be an m x n matrix and k be any number called a scalar. Then the matrix obtained by multiplying every element of A by k is called the scalar multiple of A by k and is denoted by kA. Thus, kA = [k a i j ] m x ..
