I have to import text file and then find the centroid value of the matrix

This is the code I wrote but it doesn't rum Please help me

for n = 1:5
data=['C:\Users\sunayana.chakradhar\Documents\MATLAB\Ascii12\f',num2str(n),'.txt'];
I= dlmread(data);
I=mean(I);
X_sum=sum(I,1); % sum of every column
Y_sum=sum(I,2); % sum of every row
X=1:120; % number of elements in x i
Y=1:120; % number of elements in y j
centX=sum((I(X,Y)*X_sum))/sum(I(X,Y));
disp centX

end

Isn't this really the same matter as your other question http://www.mathworks.co.uk/matlabcentral/answers/75752-matrix-centroid-finding-using-data-in-a-text-file ? If so then you should post it there and delete this question.
