POWER_METHOD_TEST
  C++ version:
  Test the POWER_METHOD library.

TEST01
  Use POWER_METHOD on the Fibonacci2 matrix.

  Matrix order N       = 50
  Maximum iterations   = 300
  Error tolerance      = 1e-06

  Number of iterations = 193
  CPU time             = 0.001675
  Estimated eigenvalue = 1.6180381955877
  Correct value        = 1.6180339887499
  Error                = 4.2068378527382e-06

  Sine of angle between true and estimated vectors = 4.4361935636769e-06

TEST02
  Use POWER_METHOD2 on the Fibonacci2 matrix.

  Matrix order N       = 50
  Maximum iterations   = 300
  Error tolerance      = 1e-06

  Number of iterations = 194
  CPU time             = 0.001701
  Estimated eigenvalue =   1.6180374001665  0
  Correct value        = 1.6180339887499
  Error                = 3.41141655813e-06

TEST03
  Use POWER_METHOD2 on the TRIS (tridiagonal scalar) matrix.

  Matrix order N         = 50
  Maximum iterations     = 4000
  Error tolerance        = 1e-06

  Number of iterations   = 2867
  CPU time               = 0.021823
  Estimated eigenvalue   = 10.001818146128  5.6479742734762
  Correct max eigenvalue = 10  5.6461250565986
  Error                  = 0.0025933103173949

POWER_METHOD_TEST:
  Normal end of execution.
