Matrix diagonalisation computations

  1. Sep 23, 2011 #1
    For matrix diagonalisation, is it necessary to compute the P and D matrix ?

    Once you have the eigenvectors, isn't it just simply a case of putting them into the P matrix

    Likewise, with the eigenvalues, don't you just put them along the diagonal axis of D to form D ?

    Yes, to both of your last statements. But isn't that exactly what "compute the P and D matrix" means? You "compute the P and D matrices" by finding the eigenvalues and corresponding eigenvectors of the original matrix.
