indexing in loop, cell

I have cell Z

in cell Z{1}=

Columns 1 through 6

    [1x3 double]    [1x3 double]    [1x3 double]    [1x3 double]    [1x3 double]    [1x3 double]

Column 7

    [1x3 double]

Z{2}= [1x3 double]    [1x3 double]

MAXP= (max count object in cell Z{1} have 7 object
                           Z{2} have 2 oject)

 MAXP=1

my code:

for i=1:size(Z,2)
     if length(Z{i})>MAXP
    for j=1:length(Z{i})

      a=([Z{i}{j};M(i,:)]);
      odch(j,:)=std(a);

     end

odch

   maxval=max(max(odch));
   [i_max,j_max]=find(odch==maxval);

   for j=1:length(Z{i})
           for c=1:length(Z{i}{j})
               if j==i_max && c==j_max

                   value=Z{i}{j}(c)
               end
           end
   end

    number=value/2

W={};

       for j=1:length(Z{i})

                  if  all((Z{i}{j})>number)
                   W{i}{j}=Z{i}{j};
                  else
                      W{i+1}{j}=Z{i}{j}; 

       end
   end

       end

end

W

When i have size(Z,2)=2, I dont know how I then index W to me it do not overwrite.

I need overwrite the variable odch.

Before the first

   for j=1:length(Z{i})

add

odch = [];
