Index exceeds matrix dimensions.

Hi,

I'm using a correlation function of Matlab corr2 to track markers in a sequence of images (the sequence is called X).

While running my program, I got the error I mentioned in the title

in this line : vtemp = [xtemp(k),ytemp(k)];

The code I wrote is below :

v = [Rx,Ry];
rects_input = calc_rects(v,CORRSIZE,X(:,:,1));
sub_input0 = imcrop(X(:,:,1),rects_input);

for i = 2:size(X,3)

    clear 'r'
    sub_input=sub_input0;

    Mat_vtemp(1,:) = [Rx(1),Ry(1)];

    for j = -CORRSIZE:CORRSIZE
        for k = 1:length(Rx)
            xtemp = Rx(k)+j;
            ytemp = Ry(k)+j;
            vtemp = [xtemp(k),ytemp(k)];

            k,j,i
            rects_input_i = calc_rects(Mat_vtemp(k,:),CORRSIZE,X(:,:,i)); 
            sub_input_i = imcrop(X(:,:,i),rects_input_i(k,:)); 

            Rx = round(Rx);
            Ry = round(Ry);

            r(Rx(k)+j,Ry(k)+j) = corr2(sub_input,sub_input_i); 

        end
       Mat_vtemp(k,:) = vtemp;
       Mat_rects_input_i = rects_input_i;
       Mat_sub_input_i = sub_input_i;
    end

    r = abs(r);
        [row,col] = find(r==max(max(r)));
    figure, imagesc(X(:,:,i)), colormap gray, axis image
    hold on
    plot(row,col,'*g')
    vopt = [row,col]; % vopt : vecteur optimal
end

Any help will be appreciated :)

The line you want is:

vtemp = [xtemp,ytemp];

xtemp and ytemp are numbers not vectors

Thanks for your answer ! It works !
