Question

Consider the matrix as given below $\left[\begin{array}{ccc}1& 2& 3\\ 0& 4& 7\\ 0& 0& 3\end{array}\right]$. Which one of the following options provides the correct values of theeigen values of the matrix?

• A. 1, 4, 3
• B. 3, 7, 3
• C. 7, 3, 2
• D. 1, 2, 3

Answer 1

The correct option is A 1, 4, 3

$\therefore$ Given matrix is an U.T.M. & We know that the diagonal elements of an upper triangular matrix are eigen values. So 1, 4, 3 are the eigen values of given matrix.
