Amatrix with dimensions1x1. Its the only termais an arbitrary number._{11}

For what values ofa, this_{11}Amatrix is;

- Diagonal
- Upper triangular
- Lower triangular

By definition a 1x1 matrix will be upper and lower triangular. (But not strictly; for strictly upper and lower: [itex]a[/itex] must be 0).

A matrix is diagonal if it is triangular and normal. Normal (for a matrix whose elements lie in the domain of real numbers) means [itex]A \ A^T = A^T \ A[/itex]

Clearly any 1x1 matrix satisfies these properties, since there are no entries off the diagonal, nonzero or not.
