sum between row in matrix

for i = 1 : graph.n

for j = 1: graph.n

graph.n=10'

graph.edges = zeros( graph.n , graph.n );

A = data.cent(i,:)-data.cent(j,:);

graph.edges(i,j) = sqrt(sum(A));

end

end

hi this is my code. I want to calculate the distance between each object in a matrix data.cent by using SUM function. but keep getting

Not enough input arguments. error

can anyone help me with this? thanks.

Try using this

 for i = 1 : graph.n
    for j = 1: graph.n 
graph.n=10'
graph.edges = zeros(  graph.n , graph.n );
A(i,:) = data.cent(i,:)-data.cent(j,:); 
graph.edges(i,j) = sqrt(sum(A(:,i))); 
   end 
 end
