Interface `diagonalise`

$\begin{boxedminipage}{\textwidth} \begin{verbatim}call diagonalise(this,eval... ...agonalise(this,overlap,evals[,evecs, & err])\end{verbatim} \end{boxedminipage}$

Diagonalise a real or complex matrix.

this -- intent(in), target, type(MatrixD) or type(MatrixZ)

evals -- real(dp), intent(inout), dimension(:)

Eigenvalues

evecs -- intent(inout), target, optional, type(MatrixD) or type(MatrixZ)

Eigenvectors

err -- integer, intent(out), optional

overlap -- intent(in), type(MatrixD) or type(MatrixZ)
