Diagonal[m] gives the list of elements on the leading diagonal of the matrix m . Eigensystem[m] gives a list {values, vectors} of the eigenvalues and eigenvectors of the square matrix m . Wolfram Data Framework Semantic framework for real-world data. It then did the next-best thing it felt it could do: provide a Jordan decomposition, which turns out to be precisely the diagonalization you want. Hi all, I'm in trouble with this problem. DiagonalMatrix[list] gives a matrix with the elements of list on the leading diagonal, and zero elsewhere . Also, to Gentry...symmetric: I do not think it means what you think it means. Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. When justified, moment methods may be used to evaluate probability density and distribution functions. Symmetric matrices and orthogonal diagonalization. Wolfram Knowledgebase Curated computable knowledge powering Wolfram|Alpha. Orthogonalize[{e1, e2, ...}, f] gives an orthonormal basis found by orthogonalizing the elements ei with respect to the inner product function f . Active 6 years, 9 months ago. ... $\begingroup$ @TheMachineCharmer: isn't wolfram alpha a bit much, considering that the problem is that the polynomial has the wrong degree? Wolfram Universal Deployment System. Wolfram Engine. These methods are particularly useful when moments are the only available information on the random variable of interest. Orthogonalize[{v1, v2, ...}] gives an orthonormal basis found by orthogonalizing the vectors vi . Diagonal[m, k] gives the elements on the k\[Null]^th diagonal of m . A classic example of the technique considered here is the Gram-Charlier series representation of a probability density function. Wolfram Community forum discussion about Fast solution to an orthogonal trajectories problem. DiagonalMatrix[list, k] gives a matrix with the elements of list on the k\[Null]^th diagonal . Wolfram-alpha didn't give up when it saw it was ill-conditioned and started spouting nonsense about it being non-diagonalizable. Instant deployment across cloud, desktop, mobile, and more. Eigensystem[{m, a}] gives the generalized eigenvalues and eigenvectors of m with respect to a . It is well known (by everyone but me, it seems) that a real skew-symmetric matrix can be put in a block-diagonal form, where the diagonal matrices are real symplectic 2x2 matrices, each one multiplied by real coefficient, linked to the original matrix eigenvalues; moreover, the transformation leading to this block-diagonal form shall be orthogonal. Eigensystem[m, k] gives the eigenvalues and eigenvectors for the first k eigenvalues of m . Stay on top of important topics and build connections by joining Wolfram Community groups relevant to your interests.
