This command is used to construct a multi-point constraint between nodes.

equalDOF $rNodeTag $cNodeTag $dof1 $dof2 ...

---

$rNodeTag	integer tag identifying the retained node (rNode)
$cNodeTag	integer tag identifying the constrained node (cNode)
$dof1 $dof2 ...	nodal degrees-of-freedom that are constrained at the cNode to be the same as those at the rNode
	Valid range is from 1 through ndf, the number of nodal degrees-of-freedom.

EXAMPLE:

equalDOF 2 3 1 3 5;

1. impose the displacements at dof's 1,3 and 5 of node 3 to be the same as those of node 2.
