| Apr 10, 2013 at 17:23 | comment | added | xavierm02 | For some matrices, you have a basis of eigenvectors and that gives you a diagonal matrix in this basis. Let $A$ be the original matrix, $B$ the matrix in the eigenvectors basis and $P$ the change of basis matrix. You have $A=PBP^{-1}$. Then you can easily compute $A^n=(PBP^{-1})^n=PB^nP^{-1}$ since $B$ is diagonal so you just put that same exponent on its elements to compute $B^n$. They are useful in a more general case but it gets a bit more complicated. | |
