if i have this matrix

   M =[ 0 0 1 0 1 0 1 0 1 0 1 0 1 0 0 1
        1 1 1 0 1 1 1 1 1 1 1 1 0 1 0 1
        1 1 0 1 0 0 0 0 0 0 0 1 1 1 1 1
        0 1 0 1 1 1 0 0 1 0 0 1 1 1 1 1
        0 1 1 1 1 0 1 0 0 1 1 1 1 1 0 1
        0 0 1 1 0 1 1 0 1 1 1 0 1 0 0 1
        0 1 0 0 1 0 1 1 1 1 0 1 1 1 0 1
        0 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1
        1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
        0 0 0 0 1 1 1 1 1 1 0 0 0 0 0 1 ]
 with this code 
   [n,m]=size(M);
   c1=cell(n,m);
   maxc=1;
   for k=1:m
     a=[0 M(:,k)' 0];
     ii1=strfind(a,[0 1]);
     ii2=strfind(a,[1 0]);
     maxc=max(maxc,numel(ii1));
     c1{k}=(ii2-ii1)';
  end
   M_column=cell2mat(cellfun(@(x)[zeros(1,maxc-numel(x));x],c1,'un',0));
