pls use this matrix<pre> x = [208 40 167 180 112 70 192 215 90 19

 100 245 100 100 193 100 100 121 145 86];</pre>and find out Computation time using tic and toc
this a challenge that who can give minimum computation tilei got 
t = 6.1917e-04 sec for Intel® Core™2 CPU 6400 @ 2.13GHz 
and RAM 4GBdo yourself and update values of tNote : Sysconfig is Not an issue finally we can analyze that so u can do by ur own machine and specify ur configuration

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

      24    36   193   210   125   127   245    89    73    33
      71   107   190   177   114   245   140   100   193   145
      140   100   100    81   165    87    35    64   192   120
      245   202   167   100   181   149    38   157   100   100
      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(R) Core(TM)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

tell me how to find the 't'

Deepesh B on 25 Jul 2014

tic
Find_And_Replace(x);
t = toc;

I'm not sure how the computation time matters here. Is it just for our personal benefit? A solution will pass even if it is very slow.
