Wolfram Engine. ... $\begingroup$ @TheMachineCharmer: isn't wolfram alpha a bit much, considering that the problem is that the polynomial has the wrong degree? Orthogonalize[{v1, v2, ...}] gives an orthonormal basis found by orthogonalizing the vectors vi . Wolfram Knowledgebase Curated computable knowledge powering Wolfram|Alpha. DiagonalMatrix[list] gives a matrix with the elements of list on the leading diagonal, and zero elsewhere . Wolfram Data Framework Semantic framework for real-world data. Ask Question Asked 10 years, 1 month ago. Stay on top of important topics and build connections by joining Wolfram Community groups relevant to your interests. Also, to Gentry...symmetric: I do not think it means what you think it means. 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. Wolfram Community forum discussion about Fast solution to an orthogonal trajectories problem. A classic example of the technique considered here is the Gram-Charlier series representation of a probability density function. Wolfram Cloud. Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. These methods are particularly useful when moments are the only available information on the random variable of interest. Software engine implementing the Wolfram Language. Eigensystem[m] gives a list {values, vectors} of the eigenvalues and eigenvectors of the square matrix m . Eigensystem[{m, a}, k] gives the first k generalized eigenvalues and eigenvectors . Eigensystem[m, k] gives the eigenvalues and eigenvectors for the first k eigenvalues of m . Orthogonalize[{e1, e2, ...}, f] gives an orthonormal basis found by orthogonalizing the elements ei with respect to the inner product function f . Hi all, I'm in trouble with this problem. Symmetric matrices and orthogonal diagonalization. Instant deployment across cloud, desktop, mobile, and more. Active 6 years, 9 months ago. Diagonal[m, k] gives the elements on the k\[Null]^th diagonal of m . Eigensystem[{m, a}] gives the generalized eigenvalues and eigenvectors of m with respect to a . 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. Wolfram Universal Deployment System. When justified, moment methods may be used to evaluate probability density and distribution functions. Wolfram-alpha didn't give up when it saw it was ill-conditioned and started spouting nonsense about it being non-diagonalizable. DiagonalMatrix[list, k, n] pads with zeros to create an n*n matrix .
