eigen.Matrix
They represent the eigenvalue decomposition of a matrix.
This class of objects is returned from the
eigen.Matrix
function
to represent an eigenvalue decomposition.
The
"eigen.Matrix"
class of objects has methods for the following generic
functions:
det
,
expand
,
facmul
,
solve
The following components must be included in a legitimate
"eigen.Matrix"
object:
left
and
right
.
If the underlying matrix is complex or real with real eigenvalues,
these components are just the matrices of left and right eigenvectors
of the underlying matrix stored columnwise.
If the matrix is real but has complex eigenvalues, then these eigenvalues
will appear in complex conjugate pairs in
values
. Rather than store
a complex matrix of eigenvectors, the real and imaginary parts of the
eigenvectors for complex conjugate pairs are stored in the corresponding
columns of
left
and
right
.
