Every scalar matrix is an identity matrix
WebAug 1, 2024 · Scalar matrix. A square matrix is said to be a scalar matrix if all the main diagonal elements are equal and other elements except main diagonal are zero. The scalar matrix can also be written in form of n * I, where n is any real number and I … WebCorrect option is B) Option A: In a scalar matrix all diagonal elements should be equal but may or may not be equal to 1 only. Therefore Every scalar matrix is not a identity matrix. Option B : In a identity matrix all elements in principal diagonal are equal (equal to 1) which is a form of scalar matrix. Therefore identity matrices are scalar.
