---

Returns the eigenvector at a specified node. Coming in version 2.2.1.

nodeEigenvector $nodeTag $eigenvector <$dof>

---

$nodeTag	integer tag identifying node
$eigenvector	mode number of eigenvector to be returned
$dof	specific dof at the node (1 through ndf), (optional)

NOTE:

If optional $dof is not provided, an array containing eigenvector values for every dof at the specified node is returned.

EXAMPLE:

set eigenvector521 [nodeEigenvector 5 2 1]; #gives the value of eigenvector that corresponds to mode 2 at node 5 in dof 1
