eigenvalue calculation (square symmetric matrices only)
Find the Eigenvalues and Eigenvectors of the matrix. Uses the Jacobi method. Only suitable for small systems (dimension<20). The matrix is replaced by the matrix of eigenvectors (as columns).
- Parameters:
-
sort Sort the eigenvalues and vectors, smallest first. (default=true)
- Returns:
- Vector of eigenvalues.
