Hi sir,here i attached one code,i need to save for loop for variable 'idx' answers in one array,then i need to save 'matrix of idx' in another array.please correct my code sir

for p=1:num of frames
i1 = cc(1:96,1:96);
  i2 = cc(1:96,97:192);
  i3 = cc(97:192,1:96);
  i4 = cc(97:192,97:192);
  y = {i1, i2, i3, i4};
  for i=1:length(y)
    ui = edge(y{i},'canny');
    count(i) = numel(find(ui(:)==1));
    clear ui
  end
  idx=find(count==max(count));
  idx(1,p)=idx;
  yu(1,p)=y{idx};
end

You are trying to create an additional column with data in with idx(1,p)=idx; but each time through the p loop you are overwriting the existing variable idx(1,p) with the line idx = find(count==max(count));

Suggest changing to idxmatrix(1,p)=idx;

No sir,i need to save 'idx' values for all 'n' in one array,also i need to save 'y{idx}' matrices for all 'n' frames in another array.help me sir

[kaavya subramani]

my last two lines of code is wrong,please give alternate solution

You have no "n" in the code.
