fem1d_pack_test():
  MATLAB/Octave version 6.4.0
  Test fem1d_pack().

fem1d_pack_test01():
  local_basis_1d() evaluates the local basis functions
  for a 1D element.

  Test that the basis functions, evaluated at the nodes,
  form the identity matrix.

  Number of nodes = 4

  Node coordinates:

         1    1.000
         2    2.000
         3    4.000
         4    4.500

  A(I,J) = PHI(I) at node (J):

    1.000   -0.000    0.000   -0.000
    0.000    1.000   -0.000    0.000
   -0.000    0.000    1.000   -0.000
    0.000   -0.000    0.000    1.000

  The PHI functions should sum to 1 at random X values:

       X        Sum ( PHI(:)(X) )
