Question

The matrix A=[0 0 5 0 5 0 5 0 0] is a (A) scalar matrix (B) diagonal matrix (C) unit matrix (D) square matrix

Tardigrade Admin · Accepted Answer

Consider the matrix A=[0 0 5 0 5 0 5 0 0] This matrix is not a diagonal matrix and hence cannot be a scalar and unit matrix, because its non-diagonal elements are non-zero. ∴ It is just a square matrix.

Consider the matrix $A = ⎣ ⎡ 005050500 ⎦ ⎤$
This matrix is not a diagonal matrix and hence cannot be a scalar and unit matrix, because its non-diagonal elements are non-zero.
$∴$ It is just a square matrix.
