MATLAB: Indexing in loop, cell

Question

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.

Answer 1

Before the first

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

add

odch = [];
