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')

??? Input argument "n" is undefined.

Error in ==> dd1 at 4 h=zeros(1, length(n)); how to solve this error

The question is now marked as Accepted so I presume you corrected it by now.
