DSGNHEP#
Dense Generalized Non-Hermitian Eigenvalue Problem.
Notes#
The problem is expressed as \(AX = BX\Lambda\), where \((A,B)\) is the input
matrix pencil. \(\Lambda\) is a diagonal matrix whose diagonal elements are the
arguments of DSSolve(). After solve, \((A,B)\) is overwritten with the
generalized (real) Schur form \((S,T) = (Z^*AQ,Z^*BQ)\), with the first
matrix being upper quasi-triangular and the second one triangular.
