if true
  data = getdata(vid,50,'double','cell');
  for i=1:5:100
    data{i}(:,:,1)=(data{i}(:,:,1))+(data{i+1}(:,:,1))+(data{i+2}(:,:,1))+ ...
                   (data{i+3}(:,:,1))+(data{i+4}(:,:,1))/5;
    data{i}(:,:,3)=(data{i}(:,:,3))+(data{i+1}(:,:,3))+(data{i+2}(:,:,3))+...
                   (data{i+3}(:,:,3))+(data{i+4}(:,:,3))/5;
    data{i}(:,:,2)=(data{i}(:,:,2))+(data{i+1}(:,:,2))+(data{i+2}(:,:,2))+...
                   (data{i+3}(:,:,2))+(data{i+4}(:,:,2))/5;
  end
end

[EDITED, Jan, code formatted - Please do this by your own, thanks!]

Hi, I am getting same error in this following loop but on selected samples , even though they are of same length, Only Some of them giving error. Here, I am trying to do framing of audio signal.Can anyone help me in this.Thank you.

n=round(length(xOut)/no_frames); %find how many samples will each frame contain
P=zeros(n,no_frames); 
for j=0:no_frames-1
    P(:,j+1)=xOut(1+n*j:n*(j+1));
end

Hi i want to 3D plot of x, y anad z and for that i have table of 1000x1 (name 'Rouser1') and have 3 variables as following

    x(n) = seq (n)-seq (n-1);
    y(n) = seq (n-1) - seq (n-2);
    z(n) = seq (n-2) - seq (n-3);
% in this seq will be  the 'values of Rouser1' and Variable of Rouser1 is 'VarName1'
% so how im suppose to make a 3D plot?
