paraheat_functional_test():
  MATLAB/Octave version 6.4.0
  Test paraheat_functional
  which accepts diffusivity parameters as input,
  solves a certain steady heat equation problem
  and returns the solution value at selected locations.

  Generating 1 random diffusivity cases.
  The initial random number seed is 123456789
  Each case involves:
    1 diffusivity seed,
    16 diffusivity parameters,
    50 sensor readings.

  Case 1, diffusivity_seed = 123456789

diffusivity_print:
  Diffusivity grid is 4 x 4
