getting an error ??? Subscript indices must either be real positive integers or logicals.

I run this code and i get the error at line 14 (at MAD=....)
function [fp,mvx,mvy]=vp_ipebma(f1,f2,N,R)
%f1: anchor frame; f2: target frame, fp: predicted image;
%mvx %mvx mvy: store the MV image ,mvy: store the MV image
%widthxheight: image size; N: block size (16 here), R: search range
height=352;
width=288;
i=0;
for i=N:N:height-N,
for j=N:N:width-N %for every block in the anchor frame
MAD_min=256*N*N;mvx=0;mvy=0;
for k=-R:1:R,
for l=-R:1:R %for every search candidate
MAD=sum(sum(abs(f1(i:i+N-1,j:j+N-1)-f2(i+k:i+k+N-1,j+l:j+l+N-1))));
%%calculate MAD for this candidate calculate MAD for this candidate
if MAD<MAD_min
MAD_min=MAD;
dy=k;
dx=l;
end
end
end
fp(i:i+N-1,j:j+N-1)= f2(i+dy:i+dy+N-1,j+dx:j+dx+N-1);
%put the best matching block in the predicted image
iblk=(floor)*(i-1)/N+1;
jblk=(floor)*(j-1)/N+1;
%block index
mvx(iblk,jblk)=dx;
mvy(iblk,jblk)=dy;
%record the estimated MV
end
end
imshow(uint8(fp));
