   end
  toc;

when I run code the programme shows me

Index exceeds matrix dimensions.

Error in finalserialcode (line 28) v1=uint16(cell2mat(look(k,2)));

I cant figure it out.any one help?

Your variable look has a length of eleimg.

You are trying to access some value between 1 and Nx*Ny*L (which is equal to 98). I suspect that eleimg is smaller than 98.
