Synopsis

[N,dNdx,J] = shapeLST (xi,xyz)

Description

SHAPELST shape functions for 6 node linear strain triangle
  [N,dNdx,J] = SHAPELST(XI,XYZ) shape functions for 6 node linear strain triangle

  Input Parameters
  ----------------
  xi   = natural (area) coordinates of element
  xyz  = nodal coordinates for element (row i for node i)
  ----------------
  Return Variables
  ----------------
  N    = shape functions in natural coordinates
  dNdx = dNdx(i,j) = derivative of shape function j with respect to geometric coordinate x_i
