Question

Distinguish between diagonal matrix scalar matrix and unit matrix​

Answer 1

Answer:

SCALAR MATRIX : A square matrix in which every non. For example , A = 5 0 0 5 is a scalar matrix of order 2 . UNIT MATRIX : A square matrix in which every non diagonal element is 0 and every diagonal element is 1 is known as a unit matrix . For example , I = 1 0 0 1 is a unit matrix of order 2

Step-by-step explanation:

Answer 2

Answer:

SCALAR MATRIX : A square matrix in which every non. For example , A = 5 0 0 5 is a scalar matrix of order 2 .

UNIT MATRIX : A square matrix in which every non diagonal element is 0 and every diagonal element is 1 is known as a unit matrix . For example , I = 1 0 0 1 is a unit matrix of order 2 .

DIAGONAL: A square matrix A is called a diagonal matrix if all the elements, except those in the leading diagonal, are zero. Thus, in a scalar matrix all the diagonal elements are equal whereas in the diagonal matrix the elements in the diagonal are not equal.
