TranDK

Purpose

transformation matrix for discrete Kirchhoff triangle constraints

Synopsis

T = TranDK (xyz)

Description

TRANDK transformation matrix for discrete Kirchhoff triangle constraints
  T = TRANDK (XYZ)
  the function sets up the 12x9 transformation matrix T from the 12 rotation dofs at the nodes
  and midsides of a 3-node triangle to the 9 nodal dofs;
