Nonsymmetric Eigenvalue Decomposition Classes

SourcePro : Linear Algebra Module User’s Guide : Class Overview : Class Groups of the Linear Algebra Module : Nonsymmetric Eigenvalue Decomposition Classes

Just as in the symmetric case, the Linear Algebra Module provides a number of decompositions and servers in a carefully layered interface. In particular, you can construct and use the Schur and Hessenberg decompositions as easily as the more standard eigenvalue decomposition. The Nonsymmetric Eigenvalue Decomposition Classes are contained in Table 5.
