Types of matrices Explained in the Video lecture

1.Square Matrix
2.Diagonal Matrix
3.Scalar Matrix
4.Identity Matrix

Square Matrix:
A matrix is said to be square if the number of rows is equal to the number of columns.

Diagonal Matrix:
A square matrix is said to be diagonal if at least one element of principal diagonal is non-zero and all the other elements are zero.

Scalar Matrix:
A diagonal matrix is said to be scalar if all of its diagonal elements are the same.

Identity or Unit Matrix:
A diagonal matrix is said to be identity if all of its diagonal elements are equal to one, denoted by I.
