MATLAB: Can any one help me to correct this code

function h=dd1(n)
h=zeros(1, length(n));
n = [1 2 3 4 5 6 7];
h(n==0) = 1;
n=-10:10;
h(n)=dd1(n-3)-2.7083*dd1(n-4)+4.1861*dd1(n-5)-3.0451*dd1(n-6)+0.73071*dd1(n-7);
stem(n, h)
xlabel('n')
ylabel('Delta Function')
Thank you.

  • function h=dd1(n)
    h=zeros(1, length(n));
    % n = [1 2 3 4 5 6 7]; % What this line is doing here?
    h(n==0) = 1;
    The call your function
    n=-10:10;
    h=dd1(n-3)-2.7083*dd1(n-4)+4.1861*dd1(n-5)-3.0451*dd1(n-6)+0.73071*dd1(n-7);
    stem(n, h)
    xlabel('n')
    ylabel('Delta Function')
