pls use this matrix

 x = [208    40   167   180   112    70   192   215    90    19
      231   100     9   100    97   100    65   100   100   100
      32   245   100    70   195   167   129   208   149   135
      233   124   239   100   203    41   178    62   140   199

      100   245   100   100   193   100   100   121   145    86];

and find out Computation time using tic and toc this a challenge that who can give minimum computation tile

i got t = 6.1917e-04 sec for Intel® Core™2 CPU 6400 @ 2.13GHz and RAM 4GB

do yourself and update values of t

Note : Sysconfig is Not an issue finally we can analyze that so u can do by ur own machine and specify ur configuration
