sparse_display_test():
  MATLAB/Octave version 4.2.2
  Test sparse_display().

sparse_display_test01()
  spy_ge() generates a sparsity plot for a matrix stored
  in general (GE) format.

  Created sparsity data file "wathen_ge_data.txt".
  Created graphics command file "wathen_ge_commands.txt".

sparse_display_test02()
  spy_file() generates a sparsity plot for a matrix for
  which there exists a file containing all the pairs
  (I,J) corresponding to nonzero entries.

  Created graphics command file "before_commands.txt".

  Created graphics command file "after_commands.txt".

sparse_display_test03()
  spy_ge() generates a sparsity plot for a matrix stored
  in general (GE) format.
  Just to orient ourselves, generate an upper triangular matrix.

  Created sparsity data file "20x30_data.txt".
  Created graphics command file "20x30_commands.txt".

sparse_display_test():
  Normal end of execution.
