We can say that a scalar matrix is a multiple of an identity matrix with any scalar quantity

so, A scalar matrix in which all the diagonals elements are the units is called as  Identity matrix   .

Answer 2

Answer:

unit matrix. In unit matrix all the diagonals ellements are unity. unit matrix is called as identity matrix.
