      DESCRIPTION...
       MINVERS calcule l'inverse multiplicatif de la matrice
       que contient le fichier A. Les enregistrements des matrices
       correspondents aux colonnes des matrices. Il doit donc y
       avoir autant d'echantillons que de variables.
 
 
      PARAMETRES...
        KIND = 0,1 SI LA MATRICE A EST GENERALE (DEFAUT)
               2,     "     "     "    SYMMETRIQUE
               3,     "     "     "    SYMMETRIQUE DEFINIE POSITIVE
 
        SI KIND EST NEGATIF LE PROGRAMME EVALUERA LA 
        PRECISION DU CALCUL ET TENTERA DE L'AMELIORER.
