decompose

public static IEigenResult decompose(AMatrix A,
                                     boolean computeVectors)

Computes the eigenvalues and eigenvectors of a matrix. Returns an object that represents the solution of the decomposition. Returns null if the decomposition fails.

Parameters:

A - The input matrix. It must be a square symmetric matrix.

computeVectors - Should it compute the eigenvectors or just eigenvalues.

Returns:

an IEigenResult object that represents the solution to the decomposition.

decompose
