MATLAB: Retrieving data and plotting it

Question

    I have 100*10 rows and column of data
    col1  col2    A     A    A    B   B   B    C    C 
    1      2    0.2    .3    .2  .1  .2  .69  .87   .8
    2      3    0.2    0.8   .7  .5  .6  .9   .5   .8
    2      4    0.2    .3    .2  .1  .2  .69  .87   .8
    5      8    0.2    0.8   .7  .5  .6  .9   .5   .8  
    from this data i have found the highest   accuracy for the for unique values in col1 and have plotted
    the res for ex is
    col1   clo2  acc
    1      2    94
    2      4    95 
    now for this data i have to find corresponging  values from first data such as 
      col1   clo2  acc       A     A   A   B   B   B    C     C 
      1      2    94        0.2   .3  .2  .1  .2  .69  .87   .8
      2      4    95        0.2   .3  .2  .1  .2  .69  .87   .8
    FROM THIS DATA I WANT TO PLOT K MEANS,is it possible

Answer 1

d = [    1      2    0.2    .3    .2  .1  .2  .69  .87   .8
2      3    0.2    0.8   .7  .5  .6  .9   .5   .8
2      4    0.2    .3    .2  .1  .2  .69  .87   .8
5      8    0.2    0.8   .7  .5  .6  .9   .5   .8]
d1 = [    1      2    94
2      4    95]
out = [d1, d(ismember(d(:,1:2),d1(:,1:2),'rows'),3:end)]
