plasma_matrix_test():
  MATLAB/Octave version 9.11.0.2358333 (R2021b) Update 7
  Test plasma_matrix()

plasma_matrix_test01():
  Linear order of spatial grid = 5
  Number of grid points is 25
  Approximate number of nonzero matrix entries is 125.
  Full storage matrix would require 625 entries.

  Norm of right hand side b is 6.1997

  Sparsity image saved as "plasma_5_sparsity.png"

  Norm of solution is 0.315693

plasma_matrix_test01():
  Linear order of spatial grid = 101
  Number of grid points is 10201
  Approximate number of nonzero matrix entries is 51005.
  Full storage matrix would require 104060401 entries.

  Norm of right hand side b is 27.7259

  Sparsity image saved as "plasma_101_sparsity.png"

  Norm of solution is 29.2756

plasma_matrix_test02():
  Linear order of spatial grid = 101
  Number of grid points is 10201
  Approximate number of nonzero matrix entries is 51005.
  Full storage matrix would require 104060401 entries.

  Norm of right hand side b is 27.7259

  Norm of backslash solution x is 29.2756
bicg stopped at iteration 20 without converging to the desired tolerance 1e-06
because the maximum number of iterations was reached.
The iterate returned (number 20) has relative residual 0.025.

  Norm of bicg solution x is 24.4076
bicg converged at iteration 39 to a solution with relative residual 9.7e-07.

  Norm of bicg+ilu solution x is 29.2756

plasma_matrix_test():
  Normal end of execution.
