pls use this matrix<pre> 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
 161 204 173 24 100 30 228 237 234 239
 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];</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

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.
