I created a zeros (n+1 by n+1) matrix. And I want the value 2*i on the row (2 : n)&(column 1:n-1) , where i is from 1 to n-1, how should I get that? Can anyone help me out?

I tried this :
for i=2:n-1
But it didnt work

Your statement isn’t clear to me. Could you give a specific example of what you want A to be with, say, n = 4.

n = 4;
A = zeros(n);
A(2:n+1:end) = 2*(1:n-1);
A(n+1,n+1) = 0;

n = 4 ;
A = zeros(n+1) ;
A(2:n,1:n-1) = repmat(2*(1:n-1),n-1,1) ;

Hi, KSSV. First of all, thanks for your effort! I might not be very clear on the requirement of the matrix. The attachment is the required matrix I need to make. And the xi is from 1 to n-1 Thanks !!!!
