Question

A square matrix B = [b_ÿ] m × m is said to be a diagonal matrix if all diagonal elements are

Options

• Zero

• One

• Half

• None of these

Answer 1

Zero

Explanation:

If all of the non-diagonal elements of a square matrix B = [b_ÿ] m × m are zero, the matrix is said to be diagonal. When i ≠ j, a matrix B = [b_ÿ] m × m is said to be a diagonal matrix if b_ij = 0.

For example, A = 4, B = `[(-1, 0),(0, 2)]`, are diagonal matrix of order 1, 2 respectively.
