+
+ Purpose:
+ ========
+ Computes the eigenvalues and left/right eigenvectors of A.
+
+ For an NxN matrix A, its eigenvalues are denoted by:
+
+ lambda(i), j = 1 ,..., N
+
+ The right eigenvectors of A are denoted by v(i) where:
+
+ A * v(i) = lambda(i) * v(i)
+
+ The left eigenvectors of A are denoted by u(i) where:
+
+ H H
+ u(i) * A = lambda(i) * u(i)
+
+ In matrix notation:
+ -1
+ A = V E V
+
+ and
+ -1
+ H H
+ A = U E U
+
+ where lambda(i) is the ith diagonal of the diagonal matrix E,
+ v(i) is the ith column of V and u(i) is the ith column of U.
+
+ The computed eigenvectors are normalized to have Euclidean norm
+ equal to 1 and largest component real.
+
+ Return Values:
+ ==============
+
+ JOB Return Values
