MATLAB: Finding the nearest valaue

nearest value

I have two sets of value 
s=
     38.9906   27.8590   18.6908   25.0184   27.5565   24.7551
     21.6141   30.9522   42.2398   52.9675   38.4323   45.0781
     39.3954   41.1888   39.0694   22.0141   34.0112   30.1668
S1= 19.0865
   36.2719
   44.6415
I HAVE to compare 1st value of S1 with first values of s and display them
for example the nearest value in s is 
   18.6908
  42.2398
  39.0694

please help

MATLAB: Finding neighbour values average of the 2d data set

x1 = floor(x(:))+1;
[ii,g] = findgroups(x1);
out = [g,splitapply(@mean,y(:),ii)];

Second variant of the output.

x1 = floor(x(:))+1;
[ii,g] = findgroups(x1);
xx = splitapply(@mean,y(:),ii);
out = [x(:),xx(ii)];

Try this:

D = [2.0000   28.2000
    2.0000   28.2000
    2.0000   25.8000
    2.0000   24.7000
    2.0000   23.5000
    2.0000   24.7000
    2.0000   28.2000
    2.0000   28.2000
    2.0000   28.2000
    2.0000   28.2000
    2.0000   28.2000
    2.0000   28.2000
         . . .      ];
     
[Du,~,idx] = unique(D(:,1));
rv = accumarray(idx, D(:,2), [], @(x){x});
Out = [Du, reshape(cell2mat(rv'), [], numel(Du))']
Out =
  Columns 1 through 11
    2.0000   28.2000   28.2000   25.8000   24.7000   23.5000   24.7000   28.2000   28.2000   28.2000   28.2000
    2.0694   28.2000   28.2000   22.3000   21.1000   20.0000   21.1000   20.0000   22.3000   25.8000   28.2000

...and so for the rest.
