I have values as
data2 = 
      [20x480 double]    [20x480 double]    [20x480 double]    [20x480 double]
      { 1x8   cell  }    { 1x8   cell  }    { 1x8   cell  }    { 1x8   cell  }
data1 = 
      [20x480 double]   
      { 1x8   cell  } 
i want to match data2 and data1 by euclidean distance and if same values are present i want to display it,plz help

What's in the 1x8 cells?

What do you want displayed? The data? The column numbers of data2 which agree with data1?

When are the values considered "the same"? When the Euclidean distance = 0 precisely or is there some tolerance>0? If the tolerance=0, why care about the Euclidean distance at all? Why not just use ISEQUAL, as in my Answer below?
