Methods summary
`private`	# `tred2( )` Symmetric Householder reduction to tridiagonal form. Symmetric Householder reduction to tridiagonal form.
`private`	# `tql2( )` Symmetric tridiagonal QL algorithm. Symmetric tridiagonal QL algorithm. This is derived from the Algol procedures tql2, by Bowdler, Martin, Reinsch, and Wilkinson, Handbook for Auto. Comp., Vol.ii-Linear Algebra, and the corresponding Fortran subroutine in EISPACK.
`private`	# `orthes( )` Nonsymmetric reduction to Hessenberg form. Nonsymmetric reduction to Hessenberg form. This is derived from the Algol procedures orthes and ortran, by Martin and Wilkinson, Handbook for Auto. Comp., Vol.ii-Linear Algebra, and the corresponding Fortran subroutines in EISPACK.
`private`	# `cdiv( $xr, $xi, $yr, $yi )` Performs complex division. Performs complex division.
`private`	# `hqr2( )` Nonsymmetric reduction from Hessenberg to real Schur form. Nonsymmetric reduction from Hessenberg to real Schur form. Code is derived from the Algol procedure hqr2, by Martin and Wilkinson, Handbook for Auto. Comp., Vol.ii-Linear Algebra, and the corresponding Fortran subroutine in EISPACK.
