ElmLenOr

Purpose

element length and x-axis orientation (direction cosines)

Synopsis

[L,dcx] = ElmLenOr (xyz)

Description

ELMLENOR element length and x-axis orientation (direction cosines)
  [L,DCX] = ELMLENOR (XYZ);
  the function determines the length L and x-axis orientation of an element
  with end node coordinates XYZ (column 1 for node i, column 2 for node j);
  the direction cosines for the element x-axis are reported in vector DCX
