QUAD_MESH_ORDER1_DISPLAY:
  MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2

  Read and plot piecewise constant data on a quadrilateral mesh.

  This program expects to find three files to read:
  * a node file,
  * an element file,
  * a value file (one value per element)

  It reads the files and displays a plot.

  Read the header of "pool_nodes.txt".
  Spatial dimension DIM_NUM = 2
  Number of points NODE_NUM = 28

  Read the data in "pool_nodes.txt".

  First 5 nodes:

  Read the header of "pool_elements.txt".

  Element order = 4
  Number of elements ELEMENT_NUM  = 18

  Read the data in "pool_elements.txt".

  First 10 elements:

MESH_BASE_ONE:
  The element indexing appears to be 1-based!
  No conversion is necessary.

  Read the header of "pool_values.txt".
  Spatial dimension = 1
  Number of values  = 18

  Read the data in "pool_values.txt".

  First 5 values:

  Row:       1
