MATLAB: When i execute function the matlab is being struck; is there any wrong with this simple code??

codeerrorfor loop

     In the following arr is a array(1-d) in which each row has three columns of 
  x-co-ordinate , y-co-ordinate and intensity values ;
  m*n is the required size of output image ie fgt here.
  In the code initially i have simply assigned all values to 65539(which is not  in range of uint16)
function [fgt]= reconstruct ( arr,m,n)
  fgt=zeros(m,n);
  fgt(:,:)=65539; % 
  l=size(arr,2)-2;
  for i=1:l
      fgt(arr(i),arr(i+1))=arr(i+2);
      i=i+3;
  end
  for i=1:m
      for j=1:n
          if(fgt(i,j)==65539)
              fgt(i,j)=0;
          end
      end
  end

Best Answer

If arr is a real array, then there will be a problem with fgt(arr(i),arr(i+1))
