for i = length(indexLabel):-1:2
        temxmat = newCenters((indexLabel(i-1)+1):indexLabel(i),1);
        temymat = newCenters((indexLabel(i-1)+1):indexLabel(i),2);
        ycoord = round(mean(newOutCenters((indexLabel(i-1)+1):indexLabel(i),2)));
        distmat = temxmat(2:end)-temxmat(1:(end-1));
        avdist = mean(distmat(distmat<threshold));
        xmat =[];
        ymat =[];
        cellReg = find(distmat(distmat>=threshold));
            for j = (length(cellReg)):-1:1
                numofpts = floor(distmat(cellReg(j))/avdist-1);
                addxmat =transpose(1:numofpts)*avdist+ones(numofpts,1)*temxmat(cellReg(j));
                xmat = [temxmat(1:j);addxmat;temxmat((j+1):length(temxmat))];
                addymat = ones(numofpts,1).*ycoord;
                ymat = [temymat(1:j);addymat;temymat((j+1):length(temymat))];
            end
         newCenters((indexLabel(i-1)+1):length(xmat),1)=xmat;
         newCenters((indexLabel(i-1)+1):length(ymat),2)=ymat;
    end
Subscripted assignment dimension mismatch.

And tell us in words what this code does. Something about circles perhaps? Make sure that if you paste your code into a new editor window (which is what we'd do) it will produce the error it said. Right now we'd just get errors about indexLabel and newOutCenters being undefined. And, like we've already asked, give the complete error message - ALL the red text, not just some of it.

Thank you very much, I have settle it down. The error results from the mismatch of the two matrix. eg. a = ones(2,2), b = ones(3), if we let a(:,1) = b, then it shows the mismatch error.
