WebSep 13, 2024 · For a symmetric 3x3 matrix, one Householder transformation will bring your matrix in tridiagonal form. The required algorithm is given (for general n × n matrices) on page 459 of Matrix Computations, 4th edition, Algorithm 8.3.1. For a 3 × 3 matrix, it's just one Householder reduction instead of a loop. WebNov 30, 2016 · This factors down to λ 3 − 3 λ 2 + 3 λ − 1 so you could say the multiplicity is 3 but you can also say that it only has 1 real root. So could I use this to find a non-diagonalizable 3x3 matrix with only 1 eigenvalue.
