psblas3/test/eigen/test_dagostino

This directory "test_dagostino" contains all the executables and scripts needed
for Dr Gregorio D'Agostino's tests.

-----------------MaxA_and_lapl_extremums---------------------
 : calculate the max eigenvalue of a matrix and the max and min
   eigenvalues of it's laplacian.

  example of use : mpirun -np 2 ./MaxA_and_lapl_extremums < maxA.inp
  		(open maxA.inp to see what input is needed for the program)

  exit : a row at the end of the file maxA_results.dat containing 
	nnzeroA  maxA  MaxLapl  2ndLapl  minLapl  execTime



------------------test_realnet---------------------------
 : does the same thing than MaxA_and_lapl_extremums. It is a little different and
  was created to be launched by step_test.sh

  example of use : not to be directly used by a user

  exit : a row at the end of the file plot_data.dat containg
        nnzeroA  maxA  MaxLapl  2ndLapl  minLapl  execTime



-------------------step_test.sh------------------------------
 : usa molte volte test_realnet su una stessa matrice troncandola a vario numero di non zeri. 
   Parte da "start" non zeri fino al "totNnzero" facendo 10000 link alla volta.

 example of use : ./step_test.sh 2 599880 7799880 step_test.inp
 		(step_test.inp contains exactly the same lines than maxA.inp)	

 L'output e il file plot_data.dat di 6 colonne e (totNzero-start)/10000 righe. Ogni riga contiene :
        nnzeroA  maxA  MaxLapl  2ndLapl  minLapl  execTime


----------------------adj_to_mm--------------------
 : reads a file containing the coordinate description of an adjacence
   sparse matrix (values are always 1) and stores it into 'a' 

  example of use : ./adj_to_mm < adj_to_mm.inp
		(open adj_to_mm.inp to know what input is needed)
