I have some set of values like
(line1) 0.1,0.69,0.81
(line2) 0.4,0.5,0.8
like this(about thousand line)
among these from line5 to line8 i have some set of values and they are repeated somewhere (not exactly same but almost same) like line32 to line35.. so how do i extract these set of values using Matlab?

Maybe this helps:
roundedTable = round(yourTable, nOfDigitsToRound);
noRepeatedRows = unique(roundedTable, 'rows');

that means for ex
  • 2.51,3.22,4.15 line1
  • 3.33,4.34,5.16 line2
then
  • 2.49,3.21,4.14 line35
  • 3.34,4.35,5.15 line36
the values are almost same.. not perfectly same.. that's what i wanted to say..

If you have R2015a or later, consider using http://www.mathworks.com/help/matlab/ref/ismembertol.html with 'ByRow' set.
